Answer:
f'(t) = -15 tons/second
Step-by-step explanation:
Using the power rule, the derivative of f(t) is ...
f'(t) = -15 . . . tons/second
f(t) is the fuel weight, so f'(t) is the rate at which fuel weight is changing. The rocket is using fuel at the rate of 15 tons per second.
_____
<em>Comment on units</em>
The units of the equation for f(t) are ...
f(t) = 2520 tons - (15 tons/second)(t seconds)
The derivative is the coefficient of (t seconds), so is (-15 tons/second).
