Interpreting a Derivative in Context

A car leaves an intersection. The distance it travels in miles is given by the function $f\left(t\right),$ where $t$ represents hours. Explain the following notations:

ⓐ $f\left(0\right)=0$
ⓑ $f^{{}^{\prime }}\left(1\right)=60$
ⓒ $f\left(1\right)=70$
ⓓ $f\left(2.5\right)=150$
