Question

D=2730 mit=9.75 hfind r

Answer 1

In order to calculate the speed r, we can use the formula:

`\text{distance}=\text{speed}\cdot\text{time}`

So, for the distance of 2730 miles and time of 9.75 hours, we have:

`\begin{gathered} 2730=r\cdot9.75 \\ r=(2730)/(9.75) \\ r=280 \end{gathered}`

Therefore the value of r is 280 mph.
