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 hour. What is their unit rate in miles per hour?

Answer 1

The unit rate in miles per hour = 1.4 miles/hr

Explanation:

Given that:

Distance walked by Boardman family = Two over five of a mile =
`(2)/(5)\ miles`

Time taken by Boardman family = Two over seven of an hour =
`(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 = (Distance)/(Time)`

Putting the values:

`\Rightarrow \frac{\frac{2}5}{\frac{2}7}\\\Rightarrow (7)/(5)\\\Rightarrow \bold{1.4\ miles/hr}`

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