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

	Japheth	Vaidev
Speed	450 m/min	250 m/min
Start time		4 min earlier
Extra distance covered at first		1000 m

(a)
Distance that Vaidev covered when he jogged 4 minutes earlier
= 4 x 250
= 1000 m

Distance that Japheth covered more than Vaidev per min
= 450 - 250
= 200 m

Time that Japheth needed to take to cover the additional 1000 m
= 1000 ÷ 200
= 5 min

(b)
Time that Vaidev would had jogged when Japheth caught up with him
= 5 + 4
= 9 min

Distance that Vaidev would have jogged when Japheth caught up with him
= 9 x 250
= 2250 m

Answer(s): (a) 5 min; (b) 2250 m
