Answer:

There are certainly many hidden costs, and you need to find them out. I am listing some. The GPU can cost a lot if you are using them for complex computing like in the case of Bitcoin. You need to pay heavy electricity bills as well. And if you want to install the webserver then as well, you need to keep your computer open all the time, and pay a good sum as an electricity bill. Many more hidden costs can be found. And one out of above is used in Schools, the webserver. Some more hidden costs can be Network cost, as the school is big, and you need to connect all through LAN, and at times we also need WAN set up. And these are another hidden cost. Various education licenses come for free, and smart classes cost as well. The video conferencing, VOIP, etc costs as well.

Scorpion4ik [409]

Answer:

$\frac{1}{3}\ m/s$

Explanation:

The computation of the velocity by using the following formula is

As we know that

$Velocity = \frac{Displacement}{Total\ time\ taken}$

where,

Displacement is 10 meters

Total time taken is 30 seconds

Now placing these values to the above formula

So, the velocity of Dash is

$= \frac{10\ meters}{30\ seconds}$

$= \frac{1}{3}\ m/s$

We simply applied the above formula so that we can get the velocity and the same is to be considered
