Jack and Tommy started jogging from the same point. Tommy started jogging 6 minutes earlier than Jack. Jack's jogging speed was 400 m/min and Tommy'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 Jack to catch up with Tommy? 
2. What distance would Tommy have jogged when Jack caught up with him?  Express your answer in meters.

	Jack	Tommy
Speed	400 m/min	100 m/min
Start time		6 min earlier
Extra distance covered at first		600 m

(a)
Distance that Tommy covered when he jogged 6 minutes earlier
= 6 x 100
= 600 m

Distance that Jack covered more than Tommy per min
= 400 - 100
= 300 m

Time that Jack needed to take to cover the additional 600 m
= 600 ÷ 300
= 2 min

(b)
Time that Tommy would had jogged when Jack caught up with him
= 2 + 6
= 8 min

Distance that Tommy would have jogged when Jack caught up with him
= 8 x 100
= 800 m

Answer(s): (a) 2 min; (b) 800 m
