Answer:
- 40 °C = - 40 °F
Step-by-step explanation:
Fahrenheit, Kelvin and Celsius are the different scales of temperature in which temperature is measured.
The conversion of T( °C) to T(F) is shown below:
T (°F) = (T (°C) × 9/5) + 32
Thus, let the same temperature be x
So,





Thus, the temperature at which both are same = - 40 °C = - 40 °F
