How many minutes did Wendy need to wait for Rick? (Answer in Minutes)

Question

Wendy and Rick left the library at noon and cycled 480 meters to the town hall. Wendy cycled at a speed of 80 meters per minute. Ricks speed was 20 meters per minute slower than Wendy's. After cycling 1/4 of the distance, Wendy stopped and waited for Rick to catch up with her.

Answer 1

Wendy cycled 1/4 the distance.  1/4 of 480 is 120.

So Wendy cycled 120 meters

if she went 80 meters per minute, she took 1.5 minutes

 

Rick went 60 meters per minute.  He went 120 meters in 2 minutes

 

2 minutes - 1.5 minutes = 0.5 minutes
