Question

At a desert resort, the temperature at 7 a.m. was 3°c. the temperature increased by an average of 3.4°c each hour until it reached 30.2°c. how long did it take to reach this temperature? write an expression only to solve this question.

Answer 1

It takes 8 hours for the temperature to reach 30.2°C.

Step-by-step explanation:

To find how long it takes for the temperature to reach 30.2°C, we can set up an equation.

Let x represent the number of hours it takes.

Starting at 3°C, the temperature increases by 3.4°C each hour.

So the equation is: 3 + 3.4x = 30.2

To solve for x, we can subtract 3 from both sides to isolate the term with x: 3.4x = 27.2

Then, divide both sides by 3.4 to solve for x: x = 8

Therefore, it takes 8 hours for the temperature to reach 30.2°C.
