please solve .

Answer 1

Answer: 10 kms

Step-by-step explanation:

See we know that

distance = speed × time

Let's take time to be x when his speed is 4kmph. So the time becomes

(x - 1/2) when the speed is 5kmph.

Now distance in first case will be 4x

and distance in second case will be 5(x - 1/2) . But distance in both case is equal.

So we can write

4x = 5x - 5/2

=> x = 5/2

This we have time 5/2 hrs when speed is 4kmph.

We can use this to find distance using d = s × t

Thus distance = 4 × 5/2 => 10 kms
