Jeremy and Henry started jogging from the same point. Henry started jogging 4 minutes earlier than Jeremy. Jeremy's jogging speed was 400 m/min and Henry's jogging speed was 300 m/min. They went in the same direction and did not change their speeds throughout.

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

	Jeremy	Henry
Speed	400 m/min	300 m/min
Start time		4 min earlier
Extra distance covered at first		1200 m

(a)
Distance that Henry covered when he jogged 4 minutes earlier
= 4 x 300
= 1200 m

Distance that Jeremy covered more than Henry per min
= 400 - 300
= 100 m

Time that Jeremy needed to take to cover the additional 1200 m
= 1200 ÷ 100
= 12 min

(b)
Time that Henry would had jogged when Jeremy caught up with him
= 12 + 4
= 16 min

Distance that Henry would have jogged when Jeremy caught up with him
= 16 x 300
= 4800 m

Answer(s): (a) 12 min; (b) 4800 m
