Perry and Ben started jogging from the same point. Ben started jogging 4 minutes earlier than Perry. Perry's jogging speed was 400 m/min and Ben's jogging speed was 200 m/min. They went in the same direction and did not change their speeds throughout.

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

	Perry	Ben
Speed	400 m/min	200 m/min
Start time		4 min earlier
Extra distance covered at first		800 m

(a)
Distance that Ben covered when he jogged 4 minutes earlier
= 4 x 200
= 800 m

Distance that Perry covered more than Ben per min
= 400 - 200
= 200 m

Time that Perry needed to take to cover the additional 800 m
= 800 ÷ 200
= 4 min

(b)
Time that Ben would had jogged when Perry caught up with him
= 4 + 4
= 8 min

Distance that Ben would have jogged when Perry caught up with him
= 8 x 200
= 1600 m

Answer(s): (a) 4 min; (b) 1600 m
