Carl and Archie started jogging from the same point. Archie started jogging 8 minutes earlier than Carl. Carl's jogging speed was 400 m/min and Archie's jogging speed was 350 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 Archie? 
2. What distance would Archie have jogged when Carl caught up with him?  Express your answer in meters.

	Carl	Archie
Speed	400 m/min	350 m/min
Start time		8 min earlier
Extra distance covered at first		2800 m

(a)
Distance that Archie covered when he jogged 8 minutes earlier
= 8 x 350
= 2800 m

Distance that Carl covered more than Archie per min
= 400 - 350
= 50 m

Time that Carl needed to take to cover the additional 2800 m
= 2800 ÷ 50
= 56 min

(b)
Time that Archie would had jogged when Carl caught up with him
= 56 + 8
= 64 min

Distance that Archie would have jogged when Carl caught up with him
= 64 x 350
= 22400 m

Answer(s): (a) 56 min; (b) 22400 m
