Question

During a heavy rainstorm a city in Florida received 12 1/4 inches of rain in 25 1/2 hours.What is the approximate rainfall rate in inches per hour?

Answer 1

Data:

The city received 12 (1/4) inches of rain in 25 (1/2) hours.

Procedure:

Rewriting the numbers as decimals.

`12\cdot(1)/(4)=12.25`
`25\cdot(1)/(2)=25.5`

To find the approximate rainfall rate in inches per hour, we have to do as follows:

`(12.25)/(25.5)\approx0.48(in)/(h)`

Rounding the result, we get...

`0.48\approx0.5\approx(1)/(2)`

Answer: D. about 1/2 inch per hour
