Answer:
It will take 17.5 minutes to reach 50 degrees F.
Step-by-step explanation:
Current temperature = -13 degrees F
With the engine on, the temperature goes up by 3.6°F per minute.
Let us assume that it takes x minutes to reach 50 degrees F.
So, the time taken will be =

=> 
=> 
x = 17.5 minutes
The expression that tells how much the temperature needs to change from -13°F to 50°F is : 
It will take 17.5 minutes to reach 50 degrees F.
Answer:
