John and David started jogging from the same point. David started jogging 6 minutes earlier than John. John's jogging speed was 350 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 John to catch up with David? 
2. What distance would David have jogged when John caught up with him?  Express your answer in meters.

	John	David
Speed	350 m/min	300 m/min
Start time		6 min earlier
Extra distance covered at first		1800 m

(a)
Distance that David covered when he jogged 6 minutes earlier
= 6 x 300
= 1800 m

Distance that John covered more than David per min
= 350 - 300
= 50 m

Time that John needed to take to cover the additional 1800 m
= 1800 ÷ 50
= 36 min

(b)
Time that David would had jogged when John caught up with him
= 36 + 6
= 42 min

Distance that David would have jogged when John caught up with him
= 42 x 300
= 12600 m

Answer(s): (a) 36 min; (b) 12600 m
