Glen and Henry started jogging from the same point. Henry started jogging 2 minutes earlier than Glen. Glen's jogging speed was 400 m/min and Henry'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 Glen to catch up with Henry? 
2. What distance would Henry have jogged when Glen caught up with him?  Express your answer in meters.

	Glen	Henry
Speed	400 m/min	200 m/min
Start time		2 min earlier
Extra distance covered at first		400 m

(a)
Distance that Henry covered when he jogged 2 minutes earlier
= 2 x 200
= 400 m

Distance that Glen covered more than Henry per min
= 400 - 200
= 200 m

Time that Glen needed to take to cover the additional 400 m
= 400 ÷ 200
= 2 min

(b)
Time that Henry would had jogged when Glen caught up with him
= 2 + 2
= 4 min

Distance that Henry would have jogged when Glen caught up with him
= 4 x 200
= 800 m

Answer(s): (a) 2 min; (b) 800 m
