Hurricane Kathrina dropped about 14 inches of rain over a 48 hour period. How much rain is this per hour? (round your answer to the nearest tenth)
I got 7 so I round it?
I did 14/48=x/24
solve for x
Then divided 336/48
How could you get so much as 7 in an hour when only twice that much dropped in 48 hours?
Please try again.
To calculate how much rain Hurricane Kathrina dropped per hour, you correctly set up the proportion:
14 inches / 48 hours = x inches / 24 hours
To solve for x, you can cross multiply:
14 inches * 24 hours = 48 hours * x inches
336 inches = 48x inches
Now, divide both sides of the equation by 48 to isolate x:
336 inches / 48 = x inches
7 inches = x inches
So, Hurricane Kathrina dropped an average of 7 inches of rain per hour. Correctly rounding this answer to the nearest tenth would be 7.0 inches per hour.
