Oliver and Charlie started jogging from the same point. Charlie started jogging 8 minutes earlier than Oliver. Oliver's jogging speed was 300 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 Oliver to catch up with Charlie? 
2. What distance would Charlie have jogged when Oliver caught up with him?  Express your answer in meters.

	Oliver	Charlie
Speed	300 m/min	100 m/min
Start time		8 min earlier
Extra distance covered at first		800 m

(a)
Distance that Charlie covered when he jogged 8 minutes earlier
= 8 x 100
= 800 m

Distance that Oliver covered more than Charlie per min
= 300 - 100
= 200 m

Time that Oliver needed to take to cover the additional 800 m
= 800 ÷ 200
= 4 min

(b)
Time that Charlie would had jogged when Oliver caught up with him
= 4 + 8
= 12 min

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

Answer(s): (a) 4 min; (b) 1200 m
