- Hi, I am doing problem number 2 from the end of the chapter questions in my textbook. The problem reads as such: "An 18-year-old runner can complete a 10.0-km course with an average speed of 4.39 m/s. A 50-year-old runner can cover the same distance with an average speed of 4.27 m/s. How much later (in seconds) should the younger runner start in order to finish the course at the same time as the older runner?" I am looking at the solution for the problem and I did everything right except the last step. The solution says to subtract the time found for the 18 year old to run 10km from the time found for the 50 year old to run 10km. However, I divided the anwers I found. Why are we subtracting the answers from one another and not dividing them? Thank you!arrow_forwardA race car travels northward on a straight, level track at a constant speed travels 0.745 km in 25.0 s. The return trip over the same track is made in 30.0 s.
