Chapter 2.C, Problem 9E
A Second Race. Jordan and Amari run a 200-meter race, and Jordan wins by 10 meters. They decide to run the 200-meter race again with Jordan starting 10 meters behind the starting line.
a. Assuming that both runners run at the same pace as they did in the first race, who wins the second race?
b. Suppose Jordan starts 5 meters behind the starting line in the second race. Who wins the race?
c. Suppose Jordan starts 15 meters behind the starting line in the second race. Who wins the race?
d. How far behind the starting line must Jordan start so the second race is a tie? First estimate the distance as closely as possible. Then try to find it exactly.
