Giving brainiest and 13 points! Please answer the following essay question in your own words:
Explain why the speed limit on a highway is an example of a unit rate. Give another example.

These speed limits and price rates are known as unit rates because they give us the rate per unit -- in the speed limits, the unit is hours -- in the prices, the unit is pounds. ... The speed limit of 55 miles per hour is the same as the ratio 55 miles to 1 hour.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

wait nvm i know the correct answer now its 100%   81 square feet
