Sean and Carl started jogging from the same point. Carl started jogging 4 minutes earlier than Sean. Sean's jogging speed was 250 m/min and Carl'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 Sean to catch up with Carl? 
2. What distance would Carl have jogged when Sean caught up with him?  Express your answer in meters.

	Sean	Carl
Speed	250 m/min	200 m/min
Start time		4 min earlier
Extra distance covered at first		800 m

(a)
Distance that Carl covered when he jogged 4 minutes earlier
= 4 x 200
= 800 m

Distance that Sean covered more than Carl per min
= 250 - 200
= 50 m

Time that Sean needed to take to cover the additional 800 m
= 800 ÷ 50
= 16 min

(b)
Time that Carl would had jogged when Sean caught up with him
= 16 + 4
= 20 min

Distance that Carl would have jogged when Sean caught up with him
= 20 x 200
= 4000 m

Answer(s): (a) 16 min; (b) 4000 m
