Answer 1

Answer:

Let us draw a diagram for the given situation.

Let us suppose Hamid's home is at H and David home's is at D.

Let they meet at a distance of x km from Hamid's home.

So, we have

HP = x

PD = 19- x

Now, the time taken by Hamid to reach the point P should be equal to the time taken by David to reach the point P.

So,

Time taken by Hamid to reach point P x/9

And time taken by David to reach point P 19-x/10

Therefore we have

x/9=19-x/10

Cross multiplying we get

10x = 171-9x

Solve for x

9x = 171

x =9

And time to reach both of them at P is given by

9/9

1 hour

So, both of them meet at a distance of 9 km at 10 o clock.
