Ian and George started jogging from the same point. George started jogging 7 minutes earlier than Ian. Ian's jogging speed was 400 m/min and George'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 Ian to catch up with George? 
2. What distance would George have jogged when Ian caught up with him?  Express your answer in meters.

	Ian	George
Speed	400 m/min	200 m/min
Start time		7 min earlier
Extra distance covered at first		1400 m

(a)
Distance that George covered when he jogged 7 minutes earlier
= 7 x 200
= 1400 m

Distance that Ian covered more than George per min
= 400 - 200
= 200 m

Time that Ian needed to take to cover the additional 1400 m
= 1400 ÷ 200
= 7 min

(b)
Time that George would had jogged when Ian caught up with him
= 7 + 7
= 14 min

Distance that George would have jogged when Ian caught up with him
= 14 x 200
= 2800 m

Answer(s): (a) 7 min; (b) 2800 m
