Ivan and Perry started jogging from the same point. Perry started jogging 2 minutes earlier than Ivan. Ivan'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 Ivan to catch up with Perry? 
2. What distance would Perry have jogged when Ivan caught up with him?  Express your answer in meters.

	Ivan	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 Ivan covered more than Perry per min
= 200 - 100
= 100 m

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

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

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

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