Express the following as a unit rate. If necessary round to the nearest tenth. 100 miles in 2.5 hours.

Unit rate in this case will be in units of miles per hour. This can be calculates as follows by dividing the the total distance covered by total time taken to cover the distance.

The total distance covered is 100 miles, and the total time taken for this is 2,5 hours. Therefore, speed in units of miles per hour is 100 divided by 2.5, that is 40 miles per hour.

This can be expressed mathematically as:

Speed = (Distance covered)/(Time take)

= 100/2.5 = 40.0 miles per hour.
