Andy and David started jogging from the same point. David started jogging 2 minutes earlier than Andy. Andy's jogging speed was 500 m/min and David's jogging speed was 300 m/min. They went in the same direction and did not change their speeds throughout.

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

	Andy	David
Speed	500 m/min	300 m/min
Start time		2 min earlier
Extra distance covered at first		600 m

(a)
Distance that David covered when he jogged 2 minutes earlier
= 2 x 300
= 600 m

Distance that Andy covered more than David per min
= 500 - 300
= 200 m

Time that Andy needed to take to cover the additional 600 m
= 600 ÷ 200
= 3 min

(b)
Time that David would had jogged when Andy caught up with him
= 3 + 2
= 5 min

Distance that David would have jogged when Andy caught up with him
= 5 x 300
= 1500 m

Answer(s): (a) 3 min; (b) 1500 m
