Ahmad and Charlie started jogging from the same point. Charlie started jogging 5 minutes earlier than Ahmad. Ahmad's jogging speed was 200 m/min and Charlie'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 Ahmad to catch up with Charlie? 
2. What distance would Charlie have jogged when Ahmad caught up with him?  Express your answer in meters.

	Ahmad	Charlie
Speed	200 m/min	100 m/min
Start time		5 min earlier
Extra distance covered at first		500 m

(a)
Distance that Charlie covered when he jogged 5 minutes earlier
= 5 x 100
= 500 m

Distance that Ahmad covered more than Charlie per min
= 200 - 100
= 100 m

Time that Ahmad needed to take to cover the additional 500 m
= 500 ÷ 100
= 5 min

(b)
Time that Charlie would had jogged when Ahmad caught up with him
= 5 + 5
= 10 min

Distance that Charlie would have jogged when Ahmad caught up with him
= 10 x 100
= 1000 m

Answer(s): (a) 5 min; (b) 1000 m
