Question

plz tell me this answer how to solve​

Answer 1

Solution:

Speed = distance/time

Let the speed of boat be ‘a’ and speed of stream be ‘b’Relative speed of boat going upstream = a – b

Relative speed of boat going downstream = a + b

Given, boat goes 30 km upstream and 44 km downstream in 10 hours.

In 13 hours, it can go 40 km upstream and 55 km downstreamand

we know,

Speed of boat = 8 km/hr and speed of stream = 3 km/hr
