2. Snow fell consistently for 6 hours. Harps said: 'We have had 30 cm of snow in 6 hours'How much Snow per hour?

Correct Answer: Correct answer is: (C) 5 cm of snow per hour.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question involves calculating the rate of snowfall, which is a basic quantitative data problem. The rate is determined by dividing the total amount of snow by the total time.

Common Mistakes: A common mistake would be to misinterpret the total amount of snow as the rate per hour, leading to an incorrect answer.

Explanations: To find the rate of snowfall per hour, we need to divide the total amount of snow by the total time. The total amount of snow is 30 cm, and the total time is 6 hours. Therefore, the rate of snowfall per hour is calculated as follows: \[ \text{Rate of snowfall per hour} = \frac{30 \text{ cm}}{6 \text{ hours}} = 5 \text{ cm per hour} \]

Option Analysis:

Option A: 6 cm of snow per hour is incorrect because it does not match the calculation of 30 cm divided by 6 hours.
Option B: 30 cm of snow per hour is incorrect because it represents the total amount of snow, not the rate per hour.
Option C: 5 cm of snow per hour is correct because it matches the calculation of 30 cm divided by 6 hours.
