A scientist is conducting an experiment where the temperature $t$ in degrees Celsius at different instances is related to the speed $s$ in meters per second of a chemical reaction by the equation:
\[ t = 5s^2 + 20s + 15 \]
The temperature at a particular time was recorded as $t = 40$. Calculate the speed $s$ at that time.
A) $s = 1$ m/s
B) $s = -5$ m/s
C) $s = 0$ m/s
D) $s = -1$ m/s

Present the answer in LaTex format: \boxed{Your answer}
