Ian and Seth started jogging from the same point. Seth started jogging 10 minutes earlier than Ian. Ian's jogging speed was 400 m/min and Seth's jogging speed was 150 m/min. They went in the same direction and did not change their speeds throughout.

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

	Ian	Seth
Speed	400 m/min	150 m/min
Start time		10 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Seth covered when he jogged 10 minutes earlier
= 10 x 150
= 1500 m

Distance that Ian covered more than Seth per min
= 400 - 150
= 250 m

Time that Ian needed to take to cover the additional 1500 m
= 1500 ÷ 250
= 6 min

(b)
Time that Seth would had jogged when Ian caught up with him
= 6 + 10
= 16 min

Distance that Seth would have jogged when Ian caught up with him
= 16 x 150
= 2400 m

Answer(s): (a) 6 min; (b) 2400 m
