Jack and Ahmad started jogging from the same point. Ahmad started jogging 4 minutes earlier than Jack. Jack's jogging speed was 350 m/min and Ahmad's jogging speed was 150 m/min. They went in the same direction and did not change their speeds throughout.

1. How long did it take for Jack to catch up with Ahmad? 
2. What distance would Ahmad have jogged when Jack caught up with him?  Express your answer in meters.

	Jack	Ahmad
Speed	350 m/min	150 m/min
Start time		4 min earlier
Extra distance covered at first		600 m

(a)
Distance that Ahmad covered when he jogged 4 minutes earlier
= 4 x 150
= 600 m

Distance that Jack covered more than Ahmad per min
= 350 - 150
= 200 m

Time that Jack needed to take to cover the additional 600 m
= 600 ÷ 200
= 3 min

(b)
Time that Ahmad would had jogged when Jack caught up with him
= 3 + 4
= 7 min

Distance that Ahmad would have jogged when Jack caught up with him
= 7 x 150
= 1050 m

Answer(s): (a) 3 min; (b) 1050 m
