Justin and Albert started jogging from the same point. Albert started jogging 4 minutes earlier than Justin. Justin's jogging speed was 300 m/min and Albert's jogging speed was 200 m/min. They went in the same direction and did not change their speeds throughout.

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

	Justin	Albert
Speed	300 m/min	200 m/min
Start time		4 min earlier
Extra distance covered at first		800 m

(a)
Distance that Albert covered when he jogged 4 minutes earlier
= 4 x 200
= 800 m

Distance that Justin covered more than Albert per min
= 300 - 200
= 100 m

Time that Justin needed to take to cover the additional 800 m
= 800 ÷ 100
= 8 min

(b)
Time that Albert would had jogged when Justin caught up with him
= 8 + 4
= 12 min

Distance that Albert would have jogged when Justin caught up with him
= 12 x 200
= 2400 m

Answer(s): (a) 8 min; (b) 2400 m
