Answer:
0.53 inches per hour
Step-by-step explanation:
There is a difference in the typed numbers and your attached picture. I'm going to assume the numbers in the picture are the correct one.
Given:
inches of rain that fell = 2 1/2 inches
duration = 4 3/4 hrs
hence the unit rate in inches per hour
= inches of rain that fell ÷ duration
= 2 1/2 ÷ 4 3/4 (for easy mathematical manipulation, we will express the fractions as improper fractions)
= 5/2 ÷ 19/4
= 5/2 x 4/19
= 10/19
= 0.526316
= 0.53 inches per hour (rounded to nearest hundredth)
hope this helps!
