Albert and Howard started jogging from the same point. Howard started jogging 7 minutes earlier than Albert. Albert's jogging speed was 400 m/min and Howard's jogging speed was 300 m/min. They went in the same direction and did not change their speeds throughout.

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

	Albert	Howard
Speed	400 m/min	300 m/min
Start time		7 min earlier
Extra distance covered at first		2100 m

(a)
Distance that Howard covered when he jogged 7 minutes earlier
= 7 x 300
= 2100 m

Distance that Albert covered more than Howard per min
= 400 - 300
= 100 m

Time that Albert needed to take to cover the additional 2100 m
= 2100 ÷ 100
= 21 min

(b)
Time that Howard would had jogged when Albert caught up with him
= 21 + 7
= 28 min

Distance that Howard would have jogged when Albert caught up with him
= 28 x 300
= 8400 m

Answer(s): (a) 21 min; (b) 8400 m
