Valen and Billy started jogging from the same point. Billy started jogging 5 minutes earlier than Valen. Valen's jogging speed was 400 m/min and Billy's jogging speed was 200 m/min. They went in the same direction and did not change their speeds throughout.

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

	Valen	Billy
Speed	400 m/min	200 m/min
Start time		5 min earlier
Extra distance covered at first		1000 m

(a)
Distance that Billy covered when he jogged 5 minutes earlier
= 5 x 200
= 1000 m

Distance that Valen covered more than Billy per min
= 400 - 200
= 200 m

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

(b)
Time that Billy would had jogged when Valen caught up with him
= 5 + 5
= 10 min

Distance that Billy would have jogged when Valen caught up with him
= 10 x 200
= 2000 m

Answer(s): (a) 5 min; (b) 2000 m
