MCQ
At what temperature the centigrade (Celsius) and Fahrenheit, readings are the same ........ $^o$
- ✓$-40$
- B$+ 40$
- C$36.6$
- D$-37$
✓
Answer
Correct option: A.
$-40$
a
(a) $\frac{C}{5} = \frac{{F - 32}}{9}$ ==> $\frac{t}{5} = \frac{{t - 32}}{9}$ $\Rightarrow$ $t = - \,40^\circ $
(a) $\frac{C}{5} = \frac{{F - 32}}{9}$ ==> $\frac{t}{5} = \frac{{t - 32}}{9}$ $\Rightarrow$ $t = - \,40^\circ $
