Question

A boat has to run a stream to reach point Y from a point x 20 kms away the both start from point x for point y and comes back to point x in total time of 41 minutes and 40 seconds what is the speed of the boat​

Answer 1

explanation

Let x be the speed of the boat and y be the speed of the current.

Speed upstream = (x - y) km/h

Speed downstream = (x + y) km/h

According to the question,

20x−y+20x+y=2536

In this equation, there are two variables but only one equation.

So, the value of x cannot be determined.
