Howard and Ivan started jogging from the same point. Ivan started jogging 10 minutes earlier than Howard. Howard's jogging speed was 400 m/min and Ivan'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 Howard to catch up with Ivan? 
2. What distance would Ivan have jogged when Howard caught up with him?  Express your answer in meters.

	Howard	Ivan
Speed	400 m/min	350 m/min
Start time		10 min earlier
Extra distance covered at first		3500 m

(a)
Distance that Ivan covered when he jogged 10 minutes earlier
= 10 x 350
= 3500 m

Distance that Howard covered more than Ivan per min
= 400 - 350
= 50 m

Time that Howard needed to take to cover the additional 3500 m
= 3500 ÷ 50
= 70 min

(b)
Time that Ivan would had jogged when Howard caught up with him
= 70 + 10
= 80 min

Distance that Ivan would have jogged when Howard caught up with him
= 80 x 350
= 28000 m

Answer(s): (a) 70 min; (b) 28000 m
