Conversions: 24,900 miles into meters (m) (1 inch =2.54cm)
Orlov [11]

For this, we will be using dimensional analysis as such:

\frac{24900\ mi}{1}*\frac{5280\ ft}{1\ mi}*\frac{12\ in}{1\ ft}*\frac{2.54\ cm}{1\ in}*\frac{1\ m}{100\ cm}=\frac{4007266560}{100}=40072665.6\ m

In short, 24,900 miles is 40,072,665.6 (40,072,666 if rounded to the whole meter) meters.

If I were you choose a variable I would say h for hours. And h is equal to 3.

In result the whole equation would be 120 - 45 - 15 * h but since h is equal to 3 , We can write it as 120 - 45 - 15 * 3. Leaving Audrey with $30 left.

Correct me if I am wrong :)
