Valen and Sean started jogging from the same point. Sean started jogging 5 minutes earlier than Valen. Valen's jogging speed was 400 m/min and Sean'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 Valen to catch up with Sean? 
2. What distance would Sean have jogged when Valen caught up with him?  Express your answer in meters.

	Valen	Sean
Speed	400 m/min	300 m/min
Start time		5 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Sean covered when he jogged 5 minutes earlier
= 5 x 300
= 1500 m

Distance that Valen covered more than Sean per min
= 400 - 300
= 100 m

Time that Valen needed to take to cover the additional 1500 m
= 1500 ÷ 100
= 15 min

(b)
Time that Sean would had jogged when Valen caught up with him
= 15 + 5
= 20 min

Distance that Sean would have jogged when Valen caught up with him
= 20 x 300
= 6000 m

Answer(s): (a) 15 min; (b) 6000 m
