Answer:
45mph
Step-by-step explanation:
We are given that
Distance drives by a family=[tex]4\frac{1}{2}=\frac{9}{2}[/tex]miles
Time =[tex]\frac{1}{10}[/tex]
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=[tex]\frac{distance}{time}[/tex]
Using the formula then, we get
[tex]Speed=\frac{\frac{9}{2}}{\frac{1}{10}}[/tex]
[tex]speed=\frac{9}{2}\times 10=45mile/hr[/tex]
Hence, the rate of speed=45 miles/hr
