Brandon and Ken started jogging from the same point. Ken started jogging 7 minutes earlier than Brandon. Brandon's jogging speed was 450 m/min and Ken's jogging speed was 100 m/min. They went in the same direction and did not change their speeds throughout.

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

	Brandon	Ken
Speed	450 m/min	100 m/min
Start time		7 min earlier
Extra distance covered at first		700 m

(a)
Distance that Ken covered when he jogged 7 minutes earlier
= 7 x 100
= 700 m

Distance that Brandon covered more than Ken per min
= 450 - 100
= 350 m

Time that Brandon needed to take to cover the additional 700 m
= 700 ÷ 350
= 2 min

(b)
Time that Ken would had jogged when Brandon caught up with him
= 2 + 7
= 9 min

Distance that Ken would have jogged when Brandon caught up with him
= 9 x 100
= 900 m

Answer(s): (a) 2 min; (b) 900 m
