Question

if it rains 12 1/4 inches of rain in 25 1/2 hours .What is the approximate rainfall rate in inches per hour

Answer 1

Let:

y = Amount of rain

x = Time

The rainfall rate is given by:

`rain_{}fall_{\text{ }}rate=\frac{Amount_{\text{ }}of_{\text{ }}rain}{Time}`

Let's convert the mixed numbers into fractions:

`12(1)/(4)=(12\cdot4+1)/(4)=(48+1)/(4)=(49)/(4)=12.25`
`25(1)/(2)=(25\cdot2+1)/(2)=(50+1)/(2)=(51)/(2)=25.5`

Therefore:

`rain_{}fall_{\text{ }}rate=(12.25)/(25.5)\approx0.48`
