Perry and Luis started jogging from the same point. Luis started jogging 9 minutes earlier than Perry. Perry's jogging speed was 400 m/min and Luis's jogging speed was 100 m/min. They went in the same direction and did not change their speeds throughout.

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

	Perry	Luis
Speed	400 m/min	100 m/min
Start time		9 min earlier
Extra distance covered at first		900 m

(a)
Distance that Luis covered when he jogged 9 minutes earlier
= 9 x 100
= 900 m

Distance that Perry covered more than Luis per min
= 400 - 100
= 300 m

Time that Perry needed to take to cover the additional 900 m
= 900 ÷ 300
= 3 min

(b)
Time that Luis would had jogged when Perry caught up with him
= 3 + 9
= 12 min

Distance that Luis would have jogged when Perry caught up with him
= 12 x 100
= 1200 m

Answer(s): (a) 3 min; (b) 1200 m
