Harry and George started jogging from the same point. George started jogging 4 minutes earlier than Harry. Harry's jogging speed was 500 m/min and George'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 Harry to catch up with George? 
2. What distance would George have jogged when Harry caught up with him?  Express your answer in meters.

	Harry	George
Speed	500 m/min	100 m/min
Start time		4 min earlier
Extra distance covered at first		400 m

(a)
Distance that George covered when he jogged 4 minutes earlier
= 4 x 100
= 400 m

Distance that Harry covered more than George per min
= 500 - 100
= 400 m

Time that Harry needed to take to cover the additional 400 m
= 400 ÷ 400
= 1 min

(b)
Time that George would had jogged when Harry caught up with him
= 1 + 4
= 5 min

Distance that George would have jogged when Harry caught up with him
= 5 x 100
= 500 m

Answer(s): (a) 1 min; (b) 500 m
