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

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

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

Distance that Liam covered more than Seth per min
= 400 - 200
= 200 m

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

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

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

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