We are given: Degrees Celsius and degrees Fahrenheit are related by formula 

To find : Solve formula for F in terms of C.
Solution: We have , 
First we need to get rid 9 from right denominator.
In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.

9C = 5 (F-32).
Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.
9C = 5F - 160.
Adding 160 on both sides,
9C+160 = 5F - 160+160.
9C+160 =5F
Dividing both sides by 5, we get 
(9C+160)/5 =5F/5.

Splitting fraction 1/5, we get

Answer:
129.5 seconds. 
Step-by-step explanation:
C = 3.14 (450)
= 1413
1413 (.40) = 565.2
562.5 + 300 + 300 
= 1165.2
1165.2 / 9 
= 129.5 seconds.
