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 4 KMPH, Find the speed of the boat in still water Answers.
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   20/(B + C) = 1.5 * [20/(B - C)]   Solving B = 5 C   given : C is 4 KMPH   So B is 20 KMPH   20
