Question
Higher Order Thinking question
What must be the temperature in Fahrenheit, so that it will be twice its value in Celsius?
Solution
According to the question, F = 2C and C1 = C
F = `"9C"/"5" + "32"`
2c = `"9"/"5""C" + "32"`
2c – `"9"/"5""c" + "32"` ⇒`"10c–9c"/"5"` = 32 + 0
`"1c"/"5"` = 32
1 C= 32× 5
| C = 160° |
∴ F = 2C= 2×160°
| F = 320° |
