Glen and Archie started jogging from the same point. Archie started jogging 6 minutes earlier than Glen. Glen's jogging speed was 500 m/min and Archie's jogging speed was 250 m/min. They went in the same direction and did not change their speeds throughout.

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

	Glen	Archie
Speed	500 m/min	250 m/min
Start time		6 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Archie covered when he jogged 6 minutes earlier
= 6 x 250
= 1500 m

Distance that Glen covered more than Archie per min
= 500 - 250
= 250 m

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

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

Distance that Archie would have jogged when Glen caught up with him
= 12 x 250
= 3000 m

Answer(s): (a) 6 min; (b) 3000 m
