Question 2(Multiple Choice Worth 5 points) (04.01)The Boardman family walked two over five of a mile in two over seven of an hou
Zolol [24]

Answer:

The unit rate in miles per hour = <em>1.4 miles/hr</em>

Step-by-step explanation:

Given that:

Distance walked by Boardman family = Two over five of a mile = \frac{2}{5}\ miles

Time taken by Boardman family = Two over seven of an hour = \frac{2}{7}\ hour

To find:

The unit rate in the miles per hour = ?

Solution:

Formula for the rate or the speed can be given as:

Speed = \dfrac{Distance}{Time}

Putting the values:

\Rightarrow \dfrac{\frac{2}5}{\frac{2}7}\\\Rightarrow \dfrac{7}{5}\\\Rightarrow \bold{1.4\ miles/hr}

So, the unit rate in miles per hour = <em>1.4 miles/hr</em>
