Japheth and Daniel started jogging from the same point. Daniel started jogging 10 minutes earlier than Japheth. Japheth's jogging speed was 200 m/min and Daniel'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 Japheth to catch up with Daniel? 
2. What distance would Daniel have jogged when Japheth caught up with him?  Express your answer in meters.

	Japheth	Daniel
Speed	200 m/min	100 m/min
Start time		10 min earlier
Extra distance covered at first		1000 m

(a)
Distance that Daniel covered when he jogged 10 minutes earlier
= 10 x 100
= 1000 m

Distance that Japheth covered more than Daniel per min
= 200 - 100
= 100 m

Time that Japheth needed to take to cover the additional 1000 m
= 1000 ÷ 100
= 10 min

(b)
Time that Daniel would had jogged when Japheth caught up with him
= 10 + 10
= 20 min

Distance that Daniel would have jogged when Japheth caught up with him
= 20 x 100
= 2000 m

Answer(s): (a) 10 min; (b) 2000 m
