The hard disk of a computer spins at 256 rotations per second. How many degrees does the hard disk pass through in one second?
Novay_Z [31]

One rotation means going once through a circular route.

One circular route means turning around by 360°

Now we know that one rotation always makes 360°.

The hard disk rotates 256 times in 1 second.

First we shall calculate the number of degrees.

In one rotation it covers 360°.

So in 256 rotations it covers 256 × 360 = 92160°

But these 256 rotations are made in one second.

So the disk passes 92160° in one second.

Answer: The hard disk passes 92160° in one second

Sarah wants to fly to Ireland, but Dylan wants to fly to France. They only have 17 days for their trips, They live in Los Angelo
Vladimir [108]
Get more specific. Don't look at days know, look at hours. Since there are 24 hours in a day, and there are 17 days, do 17*24 to get a total of 408 hours. Divide this by 2 to get 204 hours (or 8 hours 30 minutes) for each person's trip.
