On Monday, it snowed a total of 15 inches.
On Tuesday and Wednesday, it snowed in additional 4 1/2 inches and 6 3/4 inches respectively. A weather forecaster says that over the last three days, it snowed over 2 1/2 Feet. Is this a valid claim? Justify you answer.
15 + 4 1/2 + 6 3/4 = 26 1/4 inches
2 ft = 24 inches
2 1/2 feet = 30 inches
To determine if the weather forecaster's claim that it snowed over 2 1/2 feet over the last three days is valid, we need to calculate the total snowfall in feet for Monday, Tuesday, and Wednesday.
First, let's convert the inches to feet:
15 inches = 15/12 = 1.25 feet
4 1/2 inches = 4.5/12 = 0.375 feet
6 3/4 inches = 6.75/12 = 0.5625 feet
Next, we add up the snowfall for the three days:
1.25 feet + 0.375 feet + 0.5625 feet = 2.1875 feet
According to the calculations, the total snowfall over the last three days is 2.1875 feet, which is less than 2 1/2 feet. Therefore, the weather forecaster's claim that it snowed over 2 1/2 feet is not valid.
