Japheth and Warren started jogging from the same point. Warren started jogging 10 minutes earlier than Japheth. Japheth's jogging speed was 350 m/min and Warren'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 Japheth to catch up with Warren? 
2. What distance would Warren have jogged when Japheth caught up with him?  Express your answer in meters.

	Japheth	Warren
Speed	350 m/min	300 m/min
Start time		10 min earlier
Extra distance covered at first		3000 m

(a)
Distance that Warren covered when he jogged 10 minutes earlier
= 10 x 300
= 3000 m

Distance that Japheth covered more than Warren per min
= 350 - 300
= 50 m

Time that Japheth needed to take to cover the additional 3000 m
= 3000 ÷ 50
= 60 min

(b)
Time that Warren would had jogged when Japheth caught up with him
= 60 + 10
= 70 min

Distance that Warren would have jogged when Japheth caught up with him
= 70 x 300
= 21000 m

Answer(s): (a) 60 min; (b) 21000 m
