Charlie and Ben started jogging from the same point. Ben started jogging 10 minutes earlier than Charlie. Charlie's jogging speed was 200 m/min and Ben's jogging speed was 150 m/min. They went in the same direction and did not change their speeds throughout.

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

	Charlie	Ben
Speed	200 m/min	150 m/min
Start time		10 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Ben covered when he jogged 10 minutes earlier
= 10 x 150
= 1500 m

Distance that Charlie covered more than Ben per min
= 200 - 150
= 50 m

Time that Charlie needed to take to cover the additional 1500 m
= 1500 ÷ 50
= 30 min

(b)
Time that Ben would had jogged when Charlie caught up with him
= 30 + 10
= 40 min

Distance that Ben would have jogged when Charlie caught up with him
= 40 x 150
= 6000 m

Answer(s): (a) 30 min; (b) 6000 m
