Teri begins walking at 2 miles per hour at 1:00 P. M. If Cindy leaves from the same point 30 minutes later walking at 3 miles per hour, when will she catch Teri

Therefore Cindy will catch Teri after 1 hour when she starts to walk.

Step-by-step explanation:

Assume after x hour Cindy will catch Teri.

Given that, Teri begins walking at 2 miles per hour at 1:00 pm.

Teri walks 30 minutes = 0.5 hour more than Cindy.

Teri walks (x+.5) hours.

We know that,

The distance covered by Teri in  (x+.5) hours is   miles.

The  walking speed of Cindy is 3 miles per hour.

The distance covered by Cindy in x hours is = 3x miles.

Cindy and Teri both meet at a point. So both will walk same distance.

According to the problem,

Therefore Cindy will catch Teri after 1 hour when she starts to walk.
