A bus trip of 360 miles would have taken 1 hour less if the average speed V for the trip had been greater by 5 miles per hour. What was the average speed V, in miles per hour, for the trip?	Choose the correct choice from the following options:	A) 35	B) 40	C) 45	D) 50	E) 55
The time is the distance/speed. The time difference is 1 hour.   360/V - 360/(V+5) = 1   360(V+5) - 360V = (V)(V+5)   1800 = (V)(V+5)   40*45 = (V)(V+5)   V = 40 mph   The answer is 40.
