A boat can travel 1.5 times the distance down the stream than up the stream in the same time. If the speed of the current is 2 KMPH, Find the speed of the boat in still water  Choose the most appropriate option:
A) 5
B) 10
C) 15
D) 20
E) 25
Simple question, messy language.   Lets say boat's speed is B and current's speed is C.   Upstream speed : B - C   Downstream speed : B + C   Distance will be the same both times. lets say D.   given : time it takes upstream = 1.5 times time it takes downstream   D/(10 + C) = 1.5 * [D/(10 - C)]   Solving 10 = 5 C   given : C is 2 KMPH   So 10 is 10 KMPH   10
