Final answer:
The equation that gives the amount of snow that has fallen after x hours at a rate of 2 inches in 2 hours is Amount of snow = 2x.
Step-by-step explanation:
To write an equation that gives the amount of snow that has fallen after x hours at the same rate as 2 inches in 2 hours, we can use the equation: Amount of snow = (Rate of snowfall) * (Time).
Since the rate of snowfall is 4 inches in 2 hours, we can substitute it into the equation as: Amount of snow = 4 * (x/2).
This simplifies to: Amount of snow = 2x.
