Question
Write the rate in lowest terms.During a bad storm there was 4in of rain in 12hr.
Solution
The rate of rainfall is given by the amount of rain divided by the time period. In this case, it's 4 inches of rain in 12 hours.
Step 1: Write down the given rate The rate is 4 inches of rain per 12 hours.
Step 2: Simplify the rate To simplify the rate, divide both the numerator (4 inches) and the denominator (12 hours) by their greatest common divisor. The greatest common divisor of 4 and 12 is 4.
So, divide 4 inches by 4 and 12 hours by 4:
4 inches ÷ 4 = 1 inch 12 hours ÷ 4 = 3 hours
Step 3: Write the simplified rate So, the rate of rainfall in lowest terms is 1 inch per 3 hours.

During a rainstorm, 15 litres of water fell per square metre. By how much did the water level in Michael's outdoor pool rise?
A meteorologist is studying the relationship between wind speed and the rate of evaporation of water. It was found that the rate of evaporation increases linearly with wind speed. When the wind speed was 1010 meters per second, the rate of evaporation was measured at 1515 milliliters per hour, and when the wind speed was 1515 meters per second, the rate was measured at 2020 milliliters per hour. Based on this linear relationship, what would be the expected rate of evaporation, in milliliters per hour, when the wind speed is 12.312.3 meters per second?A2.32.3 B12.312.3 C17.317.3 D22.322.3
