You place your ear onto a steel railroad track and hear the sound of a distant train through the rails At = 4.2 seconds faster than you do through the air. The speed of sound in steel is vs = 6100 m/s while in air the speed of sound is v₂ = 343 m/s. a. Write an equation for the time it takes the sound to reach you through the air if the distance to the train is represented by D. b. Write an equation for the time it takes the sound to reach you through the steel if the distance to the train is represented by D. c. Use the difference in these two times to write an equation for the distance to the train. d. For the given information find the distance to the train in meters.

Q3: A bus is traveling at a speed of 50 miles/h. Express this speed in S.I. units.
I did not understand this subject very well. (Average velocity, instantaneous velocity, average acceleration, instantaneous acceleration) And I am trying to understand with this question. Especially I can't get the "instantaneous" formulas in my head and I can't figure out why we did it. I would be happy if you could solve it in an explanatory way. Thanks.
At 10:11 a.m., you pass a speed radar on the freeway. At 10:31 a.m., you pass a second speed radar along the same freeway. If the second radar was located 18 miles from the first radar, and the speed limit along the entire stretch of highway is 70 mph, could you be fined for speeding based on the radar data?Find your average velocity in miles per hour (note: 20 minutes = 1/3 hour) from 10:11 a.m. to 10:31 a.m. Round to 2 decimal places if needed.
carter traveled 40 km upstream in a boat and then traveled the same distance back. The entire trip took 4 hours and 40 minutes. If the speed of the boat was 18 (km)/(h)in still water, what was the speed of the current?
Mr. Pascual and Mr. Reyes decide to go to Batangas using a car and a motorcycle, respectively. They agree to meet at UST st so that they will start traveling at the same time. However, at the time of their meet-up, Mr. Reyes is late and he said Mr. Pascual that he will catch up. Mr. Pascual then left UST and start to travel at an average speed of 45.5 kph. After 19 minutes, Mr. Reyes arrived at UST and started to travel to batangas at an average speed of 67.81 kph. What is the total distance traveled in kilometers by Mr. Reyes by the time he catch up with Mr. Pascual? NOTE: The reference point will be at UST
