Danny and Steve are running towards each other, each one from his own house. Danny can reach Steve's house in 25 minutes of running, which is half the time it takes Steve to reach Danny's house. If the two started to run at the same time, how much time longer will it take Steve to reach the halfway point between their houses than Danny to reach the halfway point between their houses?	Choose the correct answer:
A) 12.5 minutes.	B) 25 minutes	C) 35 minutes.	D) 35 minutes	E) 75 minutes
If the distance between the two houses is D. Then   Speed of Danny = (D/25)   Speed of Steve = (D/50) [ Steve takes 50 minutes to reach Danny's house. double the time taken by Danny)   Obviously speed of Danny is Twice that of Steve.   Now in order to cover distance (D/2) [They meet in middle], Steve will take:   (D/2) / (D/50) = 25 minutes.   Distance is same and Danny's speed is twice of Steve. Thus he will take 12.5 minutes to cover this same distance.   Steve take   25-12.5=
