Mark and Peter started jogging from the same point. Peter started jogging 6 minutes earlier than Mark. Mark's jogging speed was 400 m/min and Peter'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 Mark to catch up with Peter? 
2. What distance would Peter have jogged when Mark caught up with him?  Express your answer in meters.

	Mark	Peter
Speed	400 m/min	350 m/min
Start time		6 min earlier
Extra distance covered at first		2100 m

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

Distance that Mark covered more than Peter per min
= 400 - 350
= 50 m

Time that Mark needed to take to cover the additional 2100 m
= 2100 ÷ 50
= 42 min

(b)
Time that Peter would had jogged when Mark caught up with him
= 42 + 6
= 48 min

Distance that Peter would have jogged when Mark caught up with him
= 48 x 350
= 16800 m

Answer(s): (a) 42 min; (b) 16800 m
