Fred and Liam started jogging from the same point. Liam started jogging 6 minutes earlier than Fred. Fred's jogging speed was 500 m/min and Liam's jogging speed was 350 m/min. They went in the same direction and did not change their speeds throughout.

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

	Fred	Liam
Speed	500 m/min	350 m/min
Start time		6 min earlier
Extra distance covered at first		2100 m

(a)
Distance that Liam covered when he jogged 6 minutes earlier
= 6 x 350
= 2100 m

Distance that Fred covered more than Liam per min
= 500 - 350
= 150 m

Time that Fred needed to take to cover the additional 2100 m
= 2100 ÷ 150
= 14 min

(b)
Time that Liam would had jogged when Fred caught up with him
= 14 + 6
= 20 min

Distance that Liam would have jogged when Fred caught up with him
= 20 x 350
= 7000 m

Answer(s): (a) 14 min; (b) 7000 m
