rose and luke decided to take part in a twenty mile race.
Luke runs at 5mph,
Luke DATA:
rate = 5 mph ; distance = 20 miles ; time = 20/5 = 4 hrs
------------------------
while rose runs at 4mph.
Rose DATA:
rate = 4 mph ; distance = 20 miles; time = 20/4 = 5 hrs
----------------------------------------
when Luke crosses the finish line, how far will rose be from finishing?

Rose will be 1 hr. from the finish line.
Her distance from the finish line will be 4 mph * 1 hr = 4 miles.
