Carl and Ian started jogging from the same point. Ian started jogging 9 minutes earlier than Carl. Carl's jogging speed was 400 m/min and Ian'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 Carl to catch up with Ian? 
2. What distance would Ian have jogged when Carl caught up with him?  Express your answer in meters.

	Carl	Ian
Speed	400 m/min	200 m/min
Start time		9 min earlier
Extra distance covered at first		1800 m

(a)
Distance that Ian covered when he jogged 9 minutes earlier
= 9 x 200
= 1800 m

Distance that Carl covered more than Ian per min
= 400 - 200
= 200 m

Time that Carl needed to take to cover the additional 1800 m
= 1800 ÷ 200
= 9 min

(b)
Time that Ian would had jogged when Carl caught up with him
= 9 + 9
= 18 min

Distance that Ian would have jogged when Carl caught up with him
= 18 x 200
= 3600 m

Answer(s): (a) 9 min; (b) 3600 m
