Billy and Nick started jogging from the same point. Nick started jogging 7 minutes earlier than Billy. Billy's jogging speed was 450 m/min and Nick'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 Billy to catch up with Nick? 
2. What distance would Nick have jogged when Billy caught up with him?  Express your answer in meters.

	Billy	Nick
Speed	450 m/min	100 m/min
Start time		7 min earlier
Extra distance covered at first		700 m

(a)
Distance that Nick covered when he jogged 7 minutes earlier
= 7 x 100
= 700 m

Distance that Billy covered more than Nick per min
= 450 - 100
= 350 m

Time that Billy needed to take to cover the additional 700 m
= 700 ÷ 350
= 2 min

(b)
Time that Nick would had jogged when Billy caught up with him
= 2 + 7
= 9 min

Distance that Nick would have jogged when Billy caught up with him
= 9 x 100
= 900 m

Answer(s): (a) 2 min; (b) 900 m
