Question

a swimmer can swim from point x to y in 60 minutes in still water and the speed of the current 2 km/ph.it takes 3 hours from him to swim to a new place and return if the distance between x and y is 8 km then the distance from the starting point to the new place.​

Answer 2

Given:

Distance between x and y = 8 Km

Time to cover x to y = 60 min

Speed of water = 2 Km/h

Time to reach new place(n)

To Find:

Distance from x to new place n

Solution:

For Finding the distance,

We have to find the speed of the swimmer,

By using the formula,

                               $Speed = \frac{Distance}{Time}$

After substituting the values,

                                $Speed = \frac{8}{1}$                    { Since, 60 min = 1 hour

So, the Speed of the swimmer is 8 Km/h.

The distance traveled by the swimmer in 3 hours which is the distance from y to a new place is,

But the speed will increase by 2 Km/h, then the speed will be 10 Km/h

So, by using the same formula,

                                       $10 = \frac{Distance}{3}$

                            $Distance = 30~Km$

Hence the distance between x to the new place will be,

          $Distance~from~x~to~n = 8+30\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~= 38$

The distance between x to the new place is 38 Km.
