Daniel and Liam started jogging from the same point. Liam started jogging 4 minutes earlier than Daniel. Daniel's jogging speed was 300 m/min and Liam'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 Daniel to catch up with Liam? 
2. What distance would Liam have jogged when Daniel caught up with him?  Express your answer in meters.

	Daniel	Liam
Speed	300 m/min	150 m/min
Start time		4 min earlier
Extra distance covered at first		600 m

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

Distance that Daniel covered more than Liam per min
= 300 - 150
= 150 m

Time that Daniel needed to take to cover the additional 600 m
= 600 ÷ 150
= 4 min

(b)
Time that Liam would had jogged when Daniel caught up with him
= 4 + 4
= 8 min

Distance that Liam would have jogged when Daniel caught up with him
= 8 x 150
= 1200 m

Answer(s): (a) 4 min; (b) 1200 m
