Archie and George started jogging from the same point. George started jogging 4 minutes earlier than Archie. Archie's jogging speed was 300 m/min and George's jogging speed was 150 m/min. They went in the same direction and did not change their speeds throughout.

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

	Archie	George
Speed	300 m/min	150 m/min
Start time		4 min earlier
Extra distance covered at first		600 m

(a)
Distance that George covered when he jogged 4 minutes earlier
= 4 x 150
= 600 m

Distance that Archie covered more than George per min
= 300 - 150
= 150 m

Time that Archie needed to take to cover the additional 600 m
= 600 ÷ 150
= 4 min

(b)
Time that George would had jogged when Archie caught up with him
= 4 + 4
= 8 min

Distance that George would have jogged when Archie caught up with him
= 8 x 150
= 1200 m

Answer(s): (a) 4 min; (b) 1200 m
