A boat can travel with a speed of 14 km/hr in still water. If the speed of the stream is 6 km/hr, find the time taken by the boat to go 72 km downstream.
Choose the correct option:
A) 4.25 hr	B) 3.6 hr	C) 8.25 hr	D) 2.25 hr	E) 2.50 hr
speed of boat in still water = 14 km/hr   speed of the stream = 6 km/hr   Speed downstream = (14+6)=
