Question

Cassandra noticed heavy rain outside. She decided to investigate how much rain would fall in a 1/2 hour by placing an empty cup outside. After a 1/2 hour (30 minutes), she measured the height of the water in the cup. There was 9/8 inches of rain. If the rain continues to fall, what is the rate of the rain in 1 hour? [INCLUDE UNITS] *

URGENT PLEASE HELP!!

Answer 1

18/8 or 9/4 or 2 1/4 inches of rain per hour

Explanation:

Since the rain is falling at 9/8 inches per half hour, we can double that to get the inches of rain per hour.

9/8 x 2/1 = 18/8

Simplify

9/4 or 2 1/4
