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

	Billy	Oliver
Speed	300 m/min	150 m/min
Start time		2 min earlier
Extra distance covered at first		300 m

(a)
Distance that Oliver covered when he jogged 2 minutes earlier
= 2 x 150
= 300 m

Distance that Billy covered more than Oliver per min
= 300 - 150
= 150 m

Time that Billy needed to take to cover the additional 300 m
= 300 ÷ 150
= 2 min

(b)
Time that Oliver would had jogged when Billy caught up with him
= 2 + 2
= 4 min

Distance that Oliver would have jogged when Billy caught up with him
= 4 x 150
= 600 m

Answer(s): (a) 2 min; (b) 600 m
