Zeph and Albert started jogging from the same point. Albert started jogging 4 minutes earlier than Zeph. Zeph's jogging speed was 450 m/min and Albert's jogging speed was 300 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 Albert? 
2. What distance would Albert have jogged when Zeph caught up with him?  Express your answer in meters.

	Zeph	Albert
Speed	450 m/min	300 m/min
Start time		4 min earlier
Extra distance covered at first		1200 m

(a)
Distance that Albert covered when he jogged 4 minutes earlier
= 4 x 300
= 1200 m

Distance that Zeph covered more than Albert per min
= 450 - 300
= 150 m

Time that Zeph needed to take to cover the additional 1200 m
= 1200 ÷ 150
= 8 min

(b)
Time that Albert would had jogged when Zeph caught up with him
= 8 + 4
= 12 min

Distance that Albert would have jogged when Zeph caught up with him
= 12 x 300
= 3600 m

Answer(s): (a) 8 min; (b) 3600 m
