John and Lee started jogging from the same point. Lee started jogging 10 minutes earlier than John. John's jogging speed was 300 m/min and Lee'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 John to catch up with Lee? 
2. What distance would Lee have jogged when John caught up with him?  Express your answer in meters.

	John	Lee
Speed	300 m/min	150 m/min
Start time		10 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Lee covered when he jogged 10 minutes earlier
= 10 x 150
= 1500 m

Distance that John covered more than Lee per min
= 300 - 150
= 150 m

Time that John needed to take to cover the additional 1500 m
= 1500 ÷ 150
= 10 min

(b)
Time that Lee would had jogged when John caught up with him
= 10 + 10
= 20 min

Distance that Lee would have jogged when John caught up with him
= 20 x 150
= 3000 m

Answer(s): (a) 10 min; (b) 3000 m
