Ben and Andy started jogging from the same point. Andy started jogging 3 minutes earlier than Ben. Ben's jogging speed was 400 m/min and Andy's jogging speed was 100 m/min. They went in the same direction and did not change their speeds throughout.

1. How long did it take for Ben to catch up with Andy? 
2. What distance would Andy have jogged when Ben caught up with him?  Express your answer in meters.

	Ben	Andy
Speed	400 m/min	100 m/min
Start time		3 min earlier
Extra distance covered at first		300 m

(a)
Distance that Andy covered when he jogged 3 minutes earlier
= 3 x 100
= 300 m

Distance that Ben covered more than Andy per min
= 400 - 100
= 300 m

Time that Ben needed to take to cover the additional 300 m
= 300 ÷ 300
= 1 min

(b)
Time that Andy would had jogged when Ben caught up with him
= 1 + 3
= 4 min

Distance that Andy would have jogged when Ben caught up with him
= 4 x 100
= 400 m

Answer(s): (a) 1 min; (b) 400 m
