Julian and Mark started jogging from the same point. Mark started jogging 2 minutes earlier than Julian. Julian's jogging speed was 450 m/min and Mark's jogging speed was 350 m/min. They went in the same direction and did not change their speeds throughout.

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

	Julian	Mark
Speed	450 m/min	350 m/min
Start time		2 min earlier
Extra distance covered at first		700 m

(a)
Distance that Mark covered when he jogged 2 minutes earlier
= 2 x 350
= 700 m

Distance that Julian covered more than Mark per min
= 450 - 350
= 100 m

Time that Julian needed to take to cover the additional 700 m
= 700 ÷ 100
= 7 min

(b)
Time that Mark would had jogged when Julian caught up with him
= 7 + 2
= 9 min

Distance that Mark would have jogged when Julian caught up with him
= 9 x 350
= 3150 m

Answer(s): (a) 7 min; (b) 3150 m
