Starting at 1:00 p.m., the temperature changes -4 degrees Fahrenheit per hour. Write and solve an equation to find how many hours it will take to reach -1 degrees Fahrenheit.
To find the number of hours it will take to reach -1 degrees Fahrenheit, we need to set up an equation using the given information.
Let's assume the number of hours it will take to reach -1 degrees Fahrenheit is represented by "x".
Given that the temperature changes -4 degrees Fahrenheit per hour, we can set up the equation:
-4x = -1
We can solve this equation for "x" by dividing both sides of the equation by -4:
x = -1 / -4
Simplifying the right side of the equation:
x = 1/4
So, it will take 1/4 of an hour or 15 minutes to reach -1 degrees Fahrenheit from 1:00 p.m.
no way to tell. If the temperature is T at 1 pm, then
T - 4x = -1
