Apiece of data on the edge of a performance hard drive platter in a computer moves at about 1319
inches per second. convert this rate to miles per hour.

74.94 miles per hour

Step-by-step explanation:

We simply need to convert "inches per second" to "miles per hour"

We would need to know few of these:

1 mile = 5280 feet

1 feet = 12 inches

and

60 seconds = 1 minute

60 minutes = 1 hour

We setup few proportions and cancel units and multiply/divide the numbers to arrive at our answer (shown below):

So , rounded to 2 decimal places, it is 74.94 miles per hour

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
