Answer 1

cycled 480 meters but after cycling 0.25 of the distance Wendy stopped and waited for Rick to catch up 

0.25 (480) = 120 meters

Wendy cycled at a speed of 80 meters per minute = 120 /80 = 1.5 minutes
Rick's speed was 20 meters per minute slower than Wendy's = 120 / 60 = 2 minutes

so 2 minutes -  1.5 minutes = 0.5 minutes

answer
Wendy waited 0.5 minutes for Rick
