Carl and Justin started jogging from the same point. Justin started jogging 6 minutes earlier than Carl. Carl's jogging speed was 200 m/min and Justin's jogging speed was 100 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 Justin? 
2. What distance would Justin have jogged when Carl caught up with him?  Express your answer in meters.

	Carl	Justin
Speed	200 m/min	100 m/min
Start time		6 min earlier
Extra distance covered at first		600 m

(a)
Distance that Justin covered when he jogged 6 minutes earlier
= 6 x 100
= 600 m

Distance that Carl covered more than Justin per min
= 200 - 100
= 100 m

Time that Carl needed to take to cover the additional 600 m
= 600 ÷ 100
= 6 min

(b)
Time that Justin would had jogged when Carl caught up with him
= 6 + 6
= 12 min

Distance that Justin would have jogged when Carl caught up with him
= 12 x 100
= 1200 m

Answer(s): (a) 6 min; (b) 1200 m
