Question 2

A boat covers a distance of 30 kms downstream in 2 hours while it takes 6 hours to cover the same distance upstream. What is the speed of the boat in kms per hour?

Solution

Let speed of boat be V and speed of stream be U
so as per case 1
Downstream i.e V+U = 30/2 =15
And Upstream i.e V-U = 30/6 = 5
Now adding
we get 2V =2
V =10
