On a certain day, the temperature changed at a rate of -2° F per hour. How long did it take for the change in temperature to be -14° F?
-2 * t = -14
t = 7
To find out how long it took for the change in temperature to be -14°F, we can use the formula:
(change in temperature) = (rate of change) * (time)
In this case, the change is -14° F and the rate of change is -2° F per hour. So the equation becomes:
-14 = -2 * (time)
To solve for time, we can divide both sides of the equation by -2:
-14 / -2 = time
This simplifies to:
7 = time
Therefore, it took 7 hours for the change in temperature to be -14° F.
To find out how long it took for the change in temperature to be -14°F, you can use a simple mathematical calculation. The given rate of change in temperature is -2°F per hour.
Let's assume "t" represents the number of hours it took for the temperature to change by -14°F. Since we know the rate of change is -2°F per hour, we can set up the following equation:
-2°F/hour * t hours = -14°F
To solve for "t," we can divide both sides of the equation by -2°F/hour:
t = -14°F / -2°F/hour
Simplifying the equation, we get:
t = 7 hours
Therefore, it took 7 hours for the change in temperature to be -14°F.
