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?

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 × time

Let the time taken by bicyclists = t

We have to calculate the time when they 20 miles apart this means they have covered the distance of 200 - 20 = 180 miles

t(12mph) + t(6mph) = 180

18t = 180

t =

t = 10 hours

It will take 10 hours to both the bicyclists before they are 20 miles apart.

10 hours

Step-by-step explanation:

T=180/18=10!
