Question

a family drives 4 \\( \frac{1}{2} \\) miles in \\( \frac{1}{10} \\) of an hour. how many... (part of the text is obscured by reflection)

Explanation:

Step1: Convert mixed number to fraction

$4\frac{1}{2} = \frac{9}{2}$ miles

Step2: Set up speed formula (distance/time)

$\text{Speed} = \frac{\frac{9}{2}}{\frac{1}{10}}$

Step3: Divide fractions (multiply by reciprocal)

$\text{Speed} = \frac{9}{2} \times 10 = 45$

Answer:

45 miles per hour
