32.142857 miles per hour

Step-by-step explanation:

This is the answer because:

This is a fraction equal to

225 miles ÷ 7 hours

We want a unit rate where 1 is in the denominator, so we divide top and bottom by 7 .

225/7 = 225/7 and 7/7 = 32.142857/1

Therefore, the answer is 32.142857 miles per hour.

Hope this helps!

The equivalent equation of $d=\frac{m}{V}$ is $V=\frac{m}{d}$ .

Step-by-step explanation:

The given equation is

$d=\frac{m}{V}$

Where d is density, m is mass and V is volume.

We have to solve this equation for V. To separate the variable V on one side multiply both sides by V.

$d\times V=\frac{m}{V}\times V$

dV=m

Diven both sides by d.

$\frac{dV}{d}=\frac{m}{d}$

$V=\frac{m}{d}$

Therefore the equivalent equation of the given equation is $V=\frac{m}{d}$ .
