Lee and Zeph started jogging from the same point. Zeph started jogging 10 minutes earlier than Lee. Lee's jogging speed was 400 m/min and Zeph'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 Lee to catch up with Zeph? 
2. What distance would Zeph have jogged when Lee caught up with him?  Express your answer in meters.

	Lee	Zeph
Speed	400 m/min	150 m/min
Start time		10 min earlier
Extra distance covered at first		1500 m

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

Distance that Lee covered more than Zeph per min
= 400 - 150
= 250 m

Time that Lee needed to take to cover the additional 1500 m
= 1500 ÷ 250
= 6 min

(b)
Time that Zeph would had jogged when Lee caught up with him
= 6 + 10
= 16 min

Distance that Zeph would have jogged when Lee caught up with him
= 16 x 150
= 2400 m

Answer(s): (a) 6 min; (b) 2400 m
