John and Dylan started jogging from the same point. Dylan started jogging 4 minutes earlier than John. John's jogging speed was 450 m/min and Dylan'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 Dylan? 
2. What distance would Dylan have jogged when John caught up with him?  Express your answer in meters.

	John	Dylan
Speed	450 m/min	300 m/min
Start time		4 min earlier
Extra distance covered at first		1200 m

(a)
Distance that Dylan covered when he jogged 4 minutes earlier
= 4 x 300
= 1200 m

Distance that John covered more than Dylan per min
= 450 - 300
= 150 m

Time that John needed to take to cover the additional 1200 m
= 1200 ÷ 150
= 8 min

(b)
Time that Dylan would had jogged when John caught up with him
= 8 + 4
= 12 min

Distance that Dylan would have jogged when John caught up with him
= 12 x 300
= 3600 m

Answer(s): (a) 8 min; (b) 3600 m
