Q:
# Two bicyclists are 200 miles apart when they start racing towards one another. If their speeds are 12 mph and 6 mph respectively, how much time will elapse before they are twenty miles apart?

Accepted Solution

A:

Answer:10 hours.Step-by-step explanation:Two bicyclists are 200 miles apart when they start racing towards one another.Their speeds are 12 mph and 6 mph respectively.Distance = speed × timeLet the time taken by bicyclists = tWe have to calculate the time when they 20 miles apart this means they have covered the distance of 200 - 20 = 180 milest(12mph) + t(6mph) = 18018t = 180t = [tex]\frac{180}{18}[/tex]t = 10 hoursIt will take 10 hours to both the bicyclists before they are 20 miles apart.
