A boat can travel with a speed of 10 km/hr in still water. If the speed of the stream is 8 km/hr, find the time taken by the boat to go 54 km downstream.	Answers
A) 4.25 hr
B) 5.25 hr
C) 3 hr
D) 2.25 hr
E) 2.50 hr
speed of boat in still water = 10 km/hr   speed of the stream = 8 km/hr   Speed downstream = (10+8)=
