When will the cyclists be 10 miles apart

Question

Two cyclists begin traveling in the same direction on the same bike path. One travels at 15 miles per hour, and the other travels at 12 miles per hour.

 

Answer 1

Hi, Robert.

Distance = rate x time

 

We need to find when the difference in their distances is 10 miles.

 

let t = time in hours

 

15t - 12t = 10

3t = 10

t = 10/3 = 3 1/3 hours or 3 hr 20 min.
