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

	Bryan	Perry
Speed	200 m/min	100 m/min
Start time		2 min earlier
Extra distance covered at first		200 m

(a)
Distance that Perry covered when he jogged 2 minutes earlier
= 2 x 100
= 200 m

Distance that Bryan covered more than Perry per min
= 200 - 100
= 100 m

Time that Bryan needed to take to cover the additional 200 m
= 200 ÷ 100
= 2 min

(b)
Time that Perry would had jogged when Bryan caught up with him
= 2 + 2
= 4 min

Distance that Perry would have jogged when Bryan caught up with him
= 4 x 100
= 400 m

Answer(s): (a) 2 min; (b) 400 m
