Paul and Luis started jogging from the same point. Luis started jogging 7 minutes earlier than Paul. Paul's jogging speed was 450 m/min and Luis'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 Paul to catch up with Luis? 
2. What distance would Luis have jogged when Paul caught up with him?  Express your answer in meters.

	Paul	Luis
Speed	450 m/min	300 m/min
Start time		7 min earlier
Extra distance covered at first		2100 m

(a)
Distance that Luis covered when he jogged 7 minutes earlier
= 7 x 300
= 2100 m

Distance that Paul covered more than Luis per min
= 450 - 300
= 150 m

Time that Paul needed to take to cover the additional 2100 m
= 2100 ÷ 150
= 14 min

(b)
Time that Luis would had jogged when Paul caught up with him
= 14 + 7
= 21 min

Distance that Luis would have jogged when Paul caught up with him
= 21 x 300
= 6300 m

Answer(s): (a) 14 min; (b) 6300 m
