Peter runs 100 metres in 16 seconds, while Tracy takes 20 seconds to complete the same 100 metres. By what distance will Peter beat Tracy in a 100-meter race?
Solution
In questions pertaining to races, we have to compute the distances travelled or time taken by the competitors, to find the lags in positions.
Peter takes 16 seconds to run 100 metres, how much distance has Tracy run in that time?
Tracy runs 100 meters in 20 seconds, in 16 seconds, she runs 100 * (16 / 20) = 80 meters.
Thus, Peter will beat Tracy by 20 meters in a 100 meter race.
