Jeremy and Tim started jogging from the same point. Tim started jogging 4 minutes earlier than Jeremy. Jeremy's jogging speed was 250 m/min and Tim'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 Jeremy to catch up with Tim? 
2. What distance would Tim have jogged when Jeremy caught up with him?  Express your answer in meters.

	Jeremy	Tim
Speed	250 m/min	150 m/min
Start time		4 min earlier
Extra distance covered at first		600 m

(a)
Distance that Tim covered when he jogged 4 minutes earlier
= 4 x 150
= 600 m

Distance that Jeremy covered more than Tim per min
= 250 - 150
= 100 m

Time that Jeremy needed to take to cover the additional 600 m
= 600 ÷ 100
= 6 min

(b)
Time that Tim would had jogged when Jeremy caught up with him
= 6 + 4
= 10 min

Distance that Tim would have jogged when Jeremy caught up with him
= 10 x 150
= 1500 m

Answer(s): (a) 6 min; (b) 1500 m
