During a heavy rainstorm, a city in Florida received

Alik [6]

Answer: D. About $\frac{1}{2}$ inches per hour.

Step-by-step explanation:

1. The city received $12^{\frac{1}{4}}$ inches of rain in $25^{\frac{1}{2}}$ hours.

2. Let's write the mixed number as decimal numbers:

$12^{\frac{1}{4}}in=12.25in$

$25^{\frac{1}{2}}h=25.5h$

3. To find the approximate rainfall rate in inches per hour, you must divide 12.25 inches by 25.5 hours, as following:

$\frac{12.25in}{25.5h}=0.48\frac{in}{h}$

4. If you round the result to the nearest tenth, you obtain:

$0.5\frac{in}{h}=\frac{1}{2}\frac{in}{h}$

5. Therefore, the answer is the option D.
