Both of them meet at a distance of 9 km from Hamid's home at 10 o clock.

Step-by-step explanation:

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 \frac{x}{9}

And time taken by David to reach point P \frac{19-x}{10}

Therefore, we have

\frac{x}{9}=\frac{19-x}{10}

Cross multiplying, we get

10x = 171 - 9x

Solve for x

19x = 171\\\\x=9

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

\frac{9}{9}\\\\=1\text{ hour}

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