You take the difference of 80 and -18 which would be 98 and divide by 5.4 which equals 18.148148148.... so the answer is approximately 18 minutes

As per linear equation, It take 18.15 minutes for the radiator fluid temperature to reach 80 F.

What is a linear equation?

A linear equation is an equation that has the highest power of the variable of 1.

Given, the radiator fluid in Stanley’s car is -18 F.

The temperature goes up 5.4 F per minute.

Let, after 'x' minutes the radiator fluid temperature reaches 80 F.

Therefore, - 18 + 5.4x = 80

⇒ 5.4x = 98

⇒ x = 98/5.4

⇒ x = 18.15
