A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 6 km/hr, find the time taken by the boat to go 69 km downstream.  Choose the correct choice from the following
A) 3.6 hr B) 5.25 hr C) 8.25 hr D) 2.25 hr E) 2.50 hr
speed of boat in still water = 13 km/hr   speed of the stream = 6 km/hr   Speed downstream = (13+6)=
