On a cold january morning, the radiator fluid in christine’s truck is –13°f. with the engine on, the temperature goes up by 3.6°f per minute. how long will it take the radiator temperature to reach 50°f?

which expression tells how much the temperature needs to change from -13°f to 50°f?
which expression tells how long it will take for the temperature to change?
how much time will it take for the temperature to change?

Which expression tells how much the temperature needs to change from -13°F to 50°F?  

        50 - ( -13 )

Which expression tells how long it will take for the temperature to change?  

        50 - ( -13 ) ÷ 3.6

How much time will it take for the temperature to change?  

        17.5 minutes

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.

the answer is d
