Bryan and Billy started jogging from the same point. Billy started jogging 10 minutes earlier than Bryan. Bryan's jogging speed was 200 m/min and Billy'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 Bryan to catch up with Billy? 
2. What distance would Billy have jogged when Bryan caught up with him?  Express your answer in meters.

	Bryan	Billy
Speed	200 m/min	150 m/min
Start time		10 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Billy covered when he jogged 10 minutes earlier
= 10 x 150
= 1500 m

Distance that Bryan covered more than Billy per min
= 200 - 150
= 50 m

Time that Bryan needed to take to cover the additional 1500 m
= 1500 ÷ 50
= 30 min

(b)
Time that Billy would had jogged when Bryan caught up with him
= 30 + 10
= 40 min

Distance that Billy would have jogged when Bryan caught up with him
= 40 x 150
= 6000 m

Answer(s): (a) 30 min; (b) 6000 m
