Paul and Vaidev started jogging from the same point. Vaidev started jogging 7 minutes earlier than Paul. Paul's jogging speed was 300 m/min and Vaidev'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 Paul to catch up with Vaidev? 
2. What distance would Vaidev have jogged when Paul caught up with him?  Express your answer in meters.

	Paul	Vaidev
Speed	300 m/min	150 m/min
Start time		7 min earlier
Extra distance covered at first		1050 m

(a)
Distance that Vaidev covered when he jogged 7 minutes earlier
= 7 x 150
= 1050 m

Distance that Paul covered more than Vaidev per min
= 300 - 150
= 150 m

Time that Paul needed to take to cover the additional 1050 m
= 1050 ÷ 150
= 7 min

(b)
Time that Vaidev would had jogged when Paul caught up with him
= 7 + 7
= 14 min

Distance that Vaidev would have jogged when Paul caught up with him
= 14 x 150
= 2100 m

Answer(s): (a) 7 min; (b) 2100 m
