Michael and Harry started jogging from the same point. Harry started jogging 4 minutes earlier than Michael. Michael's jogging speed was 500 m/min and Harry'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 Michael to catch up with Harry? 
2. What distance would Harry have jogged when Michael caught up with him?  Express your answer in meters.

	Michael	Harry
Speed	500 m/min	100 m/min
Start time		4 min earlier
Extra distance covered at first		400 m

(a)
Distance that Harry covered when he jogged 4 minutes earlier
= 4 x 100
= 400 m

Distance that Michael covered more than Harry per min
= 500 - 100
= 400 m

Time that Michael needed to take to cover the additional 400 m
= 400 ÷ 400
= 1 min

(b)
Time that Harry would had jogged when Michael caught up with him
= 1 + 4
= 5 min

Distance that Harry would have jogged when Michael caught up with him
= 5 x 100
= 500 m

Answer(s): (a) 1 min; (b) 500 m
