To determine

To express: given rate as a unit rate.

Answer to Problem 31SR

  $52.6$ miles per day.

Explanation of Solution

Given information:

The given rate is

$236.7$ miles in $4.5$ days.

Calculation:

For the unit rate from rate, divide the numerator and denominator of the rate by the denominator.

Here rate is $\frac{263.7\text{mi}}{4.5\text{days}}.$

Now divide the numerator and denominator by $4.5$ .

  $\begin{array}{c}\frac{236.7\text{mi}}{4.5\text{days}}=\frac{236.7}{4.5}\text{mi/day}\\ \text{=52}\text{.6}\text{mi/day}\end{array}$

Hence, the result is $52.6$ miles per day.
