Does anyone know how to solve this?
In a 100 meter race, Allen and Bruce reached the finish line in 12 seconds and 15 seconds, respectively. When Allen finished the race, how far was Bruce from the finish line?
Assume that they each move at a constant rate.
Allen finishes in 12 seconds
Bruce still has 3 seconds to go to reach the finish his 15 second run
so Bruce still has 3/15 of the race to go 3/15 x 100 = 20 m left to run
