To cyclist begin traveling in the same direction on the same bike path one travels at 20 mph the other trails at 14 mph after how many hours will they be 15 miles apart

Respuesta :

Answer:

After 2.5 hours they will be 15 miles apart.

Step-by-step explanation:

Speed of bike = 20 mph

Speed of cycle = 14 mph

They are moving in the same direction

Relative velocity = 20 - 14 = 6 mph

We need to find after how many hours will they be 15 miles apart.

Distance = 15 miles

Velocity = 6 mph

Distance =  Velocity x Time

15 = 6 x Time

Time = 2.5 hours

After 2.5 hours they will be 15 miles apart.
