Your Answer

In the question they given the data that

speed of boat 13 km/hr and speed of stream is 4 km/hr

and they asked us to solve the time taken by the boat in down stream for a distance of 68 kms.

we know as per the formula down stream means speed of boat + speed of stream

therefore,
down stream = 13+4=17 km/hr
as per the problem we got to find time taken by boat to travel a distance of 68km down stream.

we have formula that, time=distance/speed
=68/17
=4 hours
