Math Problem Statement

Snow is falling steadily in Syracuse, New York. After 2 hours, 4 inches of snow has fallen. If it continues to snow at the same rate, how many inches of snow would you expect after 6.5 hours, and how many inches in 24 hours? Write an equation to represent the snowfall after t hours.

Solution

Let's work through the questions in the image one by one:

1. If it continues to snow at the same rate, how many inches of snow would you expect after 6.5 hours?

We can calculate the rate of snowfall using the information provided in the table. After 2 hours, 4 inches of snow has fallen. Thus, the rate of snowfall is:

Rate of snowfall=4inches2hours=2inches per hour\text{Rate of snowfall} = \frac{4 \, \text{inches}}{2 \, \text{hours}} = 2 \, \text{inches per hour}

At this rate, after 6.5 hours:

Snowfall after 6.5 hours=6.5hours×2inches per hour=13inches\text{Snowfall after 6.5 hours} = 6.5 \, \text{hours} \times 2 \, \text{inches per hour} = 13 \, \text{inches}

So, after 6.5 hours, 13 inches of snow will have fallen.


2. Write an equation that gives the amount of snow that has fallen after tt hours at this rate.

The snowfall rate is 2inches per hour2 \, \text{inches per hour}, so the total snowfall S(t)S(t) after tt hours can be expressed as:

S(t)=2tS(t) = 2t

Where:

  • S(t)S(t) is the amount of snow (in inches) after tt hours.
  • tt is the time (in hours).

3. How many inches of snow will fall in 24 hours if it continues to snow at this rate?

Using the equation S(t)=2tS(t) = 2t, we substitute t=24t = 24 hours:

S(24)=2×24=48inchesS(24) = 2 \times 24 = 48 \, \text{inches}

So, 48 inches of snow will fall in 24 hours.


Would you like further details on any of these calculations?

Here are some related questions:

  1. What would be the total snowfall after 10 hours?
  2. How would the equation change if the snowfall rate was 1.5 inches per hour?
  3. Can we determine how long it would take for 30 inches of snow to accumulate?
  4. If the snowfall rate doubled, what would the new equation for snowfall be?
  5. How would you calculate the amount of snow that falls between specific time intervals, e.g., between 3 and 5 hours?

Tip: In real-world problems involving rates, ensure you understand how to calculate the rate of change (e.g., inches per hour) and apply it consistently over time.
