Detailed Solution
Download Solution PDFGiven:
Speed of the boat in still water = 13 km/hr
Speed of the stream = 4 km/hr
Distance to be travelled downstream = 51 km
Formula Used:
Downstream speed = Speed of the boat in still water + Speed of the stream
Time taken = Distance / Speed
Calculation:
Downstream speed = 13 + 4
Downstream speed = 17 km/hr
Time taken = 51 / 17
Time taken = 3 hours
The time taken by the boat to travel 51 km downstream is 3 hours.
