A boat can travel with a speed of 24 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 196 km downstream  Choose the correct choice from the following choices.
A) 3 hours	B) 4 hours	C) 5 hours	D) 6 hours	E) 7 hours
7 hoursxplanation:   Speed of the boat in still water = 24 km/hr   speed of the stream = 4 km/hr   Speed downstream = (22+5) = 28 km/hr   Distance travelled downstream = 196 km   Time taken = distance/speed = 196/28=
