Chapter 2, Problem 53GP
A truck driver has a shipment of apples to deliver to a desti-nation 440 miles away. The trip usually takes him 8 hours. Today he finds himself daydreaming and realizes 120 miles into his trip that he is running 15 minutes later than his usual pace at this point. At what speed must he drive for the remainder of the trip to complete the trip in the usual amount of time?

Sally has a very important date at eight in the evening, but she has some errands to do first. She bicycles over to the shopping center at the rate of 6 mph. The shopping center is 8 miles away. She spends an hour and a half there, stops to talk to a friend on the way home for 10 minutes, stops for a meal that takes her 45 minutes to eat, and then spends one hour and five minutes getting dressed for her date. What time did she have to start her errands in order to be ready on time for her date?
Gaby and her cousin, Fiona, live 45 km apart. Every day, they drive by one another to get to work. Gaby leaves home at 7:00 a.m. and drives at the road speed of 60 km/h. Fiona, however, always leaves home 20 min later and therefore speeds by 10 km/h. Approximately what time will Gaby meet Fiona on the road?
We travel from Winnipeg to Regina and back. The total distance is 1100km. The return to Winnipeg is made in a snowstorm at an average speed of 20km/h slower than the outward journey. If the whole trip took 13 hours, what is the average speed in each direction?

- You and your family are going on a road trip to visit your recently married cousin in B.C. The total round trip distance is 2100 km. On the way to B.C., you encounter no setbacks and you are able to drive on average at a constant speed. On the way home from B.C., you encounter a snowstorm and your mom has to slow down to avoid getting into an accident. Thus, your average speed decreases by 10 km/h. If the total driving time was 42 hours, what was your average speed on the way to B.C.? Recall distance = speed x time.arrow_forwardA man decided to ride his car at 10 kph for the first 5 seconds. He then accelerates at 1 m/s for the next 5 seconds, 2 m/s for the next 5 seconds, 3 m/s2 for the next 5 seconds, and so on and so forth. (a) At what time will he reach a velocity of 60 kph? (b) What is the total distance (m) traveled after he has reached a velocity of 60 kph?arrow_forwardAlice left her house at 7:00 A.M. for work. Her husband found her pocketbook athome at 8:00 A.M., so he jumped into his car to try to catch up with her. If Alicetravels to work at 30 mph and her husband is traveling at 75 mph, can he catchup to her before she gets to work if her office is 60 miles from her house? If hedoes, what time does he catch up to her?arrow_forward
- Mario rides his motorcycle in going to school. He drives at an average speed of 30 kilometers per hour. The distance between his house and the school is 15 kilometers. Every time he sees his best friend Jessica walking on the road, he invites her for a ride and lowers his speed. On the other hand, he increases his speed when he wakes up late for school. a) If x represents the time it takes Mario to drive to school with the given distance of 15 kilometers, how will you represent the relationship of his speed (y) versus the time (x)?arrow_forwardA train leaves the train station at 11:30 am. It travels at a speed of 9 mph. Another train leaves the train station at 12:30 pm. It travels at a speed of 12 mph. How long will i take the second train to reach the first train. I left the 12:30 pm out the earlier question. The earlier time was something like + 0.50t?arrow_forwardEvan is just leaving his house to visit his grandma.

- A brand-new engineering hire is late for her first product development team meeting. She gets out of her car and starts running 8 mph. It is exactly 7:58 a.m., and the meeting starts at exactly 8:00 a.m. Her meeting is 510 yd away. Will she make it on time to the meeting? If so, with how much time to spare? If not, how late will she be? (Express your answer using two significant figures. Enter a negative value if the person will be late and a positive value if she will come earlier.) tarrow_forwardA men travels with a speed of 20 ms ¹ for 60 minute.

- You plan on making a one-hour stop for lunch, and two 10-minute gas/rest stops along the way. What is your revised travel time in minutes for a one-way trip? According to the trip planner, it takes 3hrs and 4 minutes one way for this trip.arrow_forwardConsider a dragster that, when the light turns green, accelerates uniformly from rest and completes a 372 meter race in a time of 6.61 seconds. a) During this period, what is the dragster's acceleration expressed as a multiple of the acceleration due to gravity, g? b) If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has traveled a total distance of 1.6km1.6km, which is approximately one mile?arrow_forwardYou are to drive to an interview in another city at a distance of 300km on an expressway. The interview is 11:15 in the morning and you plan to drive at 100kph so you leave at 8 in the morning to allow some extra time. You drive at that speed for the first 100km, but then construction work forces you to slow to 40kph for 40km. What would be the least speed needed for the rest of the trip to arrive in time for the interview?arrow_forward
