To find the rate of speed in miles per hour, you can use the formula:
[ text{Speed} = frac{text{Distance}}{text{Time}} ]
In this case, the family drives 4.5 miles in 0.1 hours.
Now, substituting the values into the formula:
[ text{Speed} = frac{4.5 text{ miles}}{0.1 text{ hours}} ]
Calculating this:
[ text{Speed} = 45 text{ miles per hour} ]
So, the family’s rate of speed is 45 miles per hour.
