Ahmad and Peter started jogging from the same point. Peter started jogging 9 minutes earlier than Ahmad. Ahmad's jogging speed was 400 m/min and Peter'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 Peter? 
2. What distance would Peter have jogged when Ahmad caught up with him?  Express your answer in meters.

	Ahmad	Peter
Speed	400 m/min	100 m/min
Start time		9 min earlier
Extra distance covered at first		900 m

(a)
Distance that Peter covered when he jogged 9 minutes earlier
= 9 x 100
= 900 m

Distance that Ahmad covered more than Peter per min
= 400 - 100
= 300 m

Time that Ahmad needed to take to cover the additional 900 m
= 900 ÷ 300
= 3 min

(b)
Time that Peter would had jogged when Ahmad caught up with him
= 3 + 9
= 12 min

Distance that Peter would have jogged when Ahmad caught up with him
= 12 x 100
= 1200 m

Answer(s): (a) 3 min; (b) 1200 m
