Question

A family drives 4 1/2 miles in 1/10 of an hour. What is their rate of speed in miles per hour?

Answer 1

45 miles

Explanation:

4.5*10=45

Answer 2

45mph

Explanation:

We are given that

Distance drives by a family=
`4(1)/(2)=(9)/(2)`miles

Time =
`(1)/(10)`

We have to find the rate of speed in miles per hour.

To find the rate of speed in miles per hour we will use the formula of speed .

Speed=
`(distance)/(time)`

Using the formula then, we get

`Speed=((9)/(2))/((1)/(10))`

`speed=(9)/(2)* 10=45mile/hr`

Hence, the rate of speed=45 miles/hr
