3 1/3
1 7/8
8/15
3/10​

Answer 1

The rate of rainfall on Friday was 3/8 inch per hour, which is obtained by dividing the total rainfall amount (3/4 inch) by the total duration of rainfall (2 hours).

Step-by-step explanation:

To find the rate of rainfall, which is measured in inches per hour, we divide the total amount of rain that fell by the total time it fell for. In this scenario, a total of 3/4 inch of rain fell over a period of 2 hours.

The calculation to find the rainfall rate per hour is as follows:

1. Start with the total rainfall amount: 3/4 inch.
2. Divide this amount by the total time: 2 hours.
3. The resulting rate is the amount of rain that falls in one hour.

The rate of rainfall per hour is 3/8 inch per hour (since 3/4 divided by 2 equals 3/8).
