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 distance is 4.5 miles, and the time is 0.1 hours (1/10 of an hour).
Now, plug in the values:
[ text{Speed} = frac{4.5 text{ miles}}{0.1 text{ hours}} ]
This simplifies to:
[ text{Speed} = 45 text{ miles per hour} ]
So the family is driving at a speed of 45 miles per hour.
