Answer: 7

Step-by-step explanation:

\frac{-14}{-2}

Both 14 and 2 are divisible by 2, so we can divide both of these numbers by 2.

\frac{-7}{-1}

Both numbers are negative, so we can divide both of these numbers by -1.

\frac{7}{1}

Answer:

It will take 4.71 hours to travel a distance of 221.43 miles

Step-by-step explanation:

Given

Distance covered in time 7.99 hours is 375.32 miles.

Now we know that speed is equal to distance per unit time.

Therefore,

$speed = \frac{distance}{time} \\= \frac{375.32}{7.99}\\=46.97\ mi/h$

Which is the constant speed, hence now time taken for a distance of 221.43 miles will be

$time = \frac{distance}{speed} \\=\frac{221.43}{46.97} \\=4.71\ h$

Therefore, the time taken to cover 221.43 miles is 4.71 hours.
