Akira is running around a circular track. Akira runs counterclockwise. From where he starts, it takes him 22 seconds to reach the easternmost point of the track. It takes him 95 seconds to run one complete lap.Bob starts running at the same time as Akira. Bob starts from the northernmost point and runs clockwise. Bob and Akira pass each other for the first time after 26 seconds. How long does Bob take to run one lap of the track? The answer to this question should be the amount of time in seconds rounded to four decimal places that it takes for Bob to run a complete lap around the circular track.
A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race.

I bought a new gas lawn mower the other day. This new mower mows faster than the old electric (environmental) one. Why, you ask? It is because the old mower cut a 21 inch path, while the new one cuts a 22 inch path. So how much time did I save? Look at some facts. My lawn is a rectangle measuring 150 feet by 105 feet I mow the lawn in strips and always in the same direction (length or width) My walking speed is 120 feet/minute It takes 5 seconds to turn around after each strip How much time did I save if I mow back and forth along the width or if I mow back and forth along the length? Pick one and figure it out. My neighbor does not like minutes the noise it makes, but I do!
