Zeph and Harry started jogging from the same point. Harry started jogging 3 minutes earlier than Zeph. Zeph's jogging speed was 300 m/min and Harry's jogging speed was 250 m/min. They went in the same direction and did not change their speeds throughout.

1. How long did it take for Zeph to catch up with Harry? 
2. What distance would Harry have jogged when Zeph caught up with him?  Express your answer in meters.

	Zeph	Harry
Speed	300 m/min	250 m/min
Start time		3 min earlier
Extra distance covered at first		750 m

(a)
Distance that Harry covered when he jogged 3 minutes earlier
= 3 x 250
= 750 m

Distance that Zeph covered more than Harry per min
= 300 - 250
= 50 m

Time that Zeph needed to take to cover the additional 750 m
= 750 ÷ 50
= 15 min

(b)
Time that Harry would had jogged when Zeph caught up with him
= 15 + 3
= 18 min

Distance that Harry would have jogged when Zeph caught up with him
= 18 x 250
= 4500 m

Answer(s): (a) 15 min; (b) 4500 m
