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

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

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

Distance that Andy covered more than Charlie per min
= 400 - 100
= 300 m

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

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

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

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