If snow is falling at a rate of \(\frac{1}{4}\) inch every 30 minutes, how much snow will fall in \(4 \frac{1}{2}\) hours?
Answer (3)
The answer is 2 1/4 inch or 2.25 inch per 4 1/2 hours
30 min = 0.5 h 4 1 in c h = 0.25 in c h 4 2 1 h = 4.5 h
0.25 in c h − 0.5 h 2 ⋅ 0.25 in c h − 2 ⋅ 0.5 h → 0.5 in c h − 1 h 0.5 in c h − 1 h 0.5 in c h − 1 h 0.5 in c h − 1 h 0.5 in c h − 1 h 0.25 in c h − 0.5 h − − − − − − − − − − − − + 2.25 in c h − 4.5 h
In 4 2 1 hours, 2 4 1 inches of snow will fall. This is calculated by converting hours to minutes and finding the number of 30-minute intervals. Each interval produces 4 1 inch of snow, totaling 2 4 1 inches for 9 intervals.
