When a snowstorm hit the town of Clarkesville, there already were 4 inches of snow on the ground. The storm lasted for 2 hours, and by the time it was over, there were at least 6 inches of snow on the ground. Which number line shows the solution set for the mean number of inches of snow per hour that could have fallen during the storm?

Rate of snow fall per hour ≥ 1 inches per hour

Step-by-step explanation:

Given:

Amount of snow already settled = 4 inches

Time period of snow fall = 2 hour

New amount of snow = least 6 inches

Computation:

Extra amount of snow ≥ New amount of snow - Amount of snow already settled

Extra amount of snow ≥ 6 - 4

Extra amount of snow ≥ 2 inches

Rate of snow fall per hour ≥ Extra amount of snow / Time period of snow fall

Rate of snow fall per hour ≥ 2 / 2

Rate of snow fall per hour ≥ 1 inches per hour
