Question

1. the water temperature at the beach started at 82 degrees, and it is rising 0.6 degrees each hour. if the water temperature is now 85 degrees, write and solve an equation to find h, the number of hours that have passed.

equation:

solution:

Explanation:

Step1: Define the temperature equation

The initial temperature is 82, it rises by 0.6 per hour, so the equation for current temperature is:
$82 + 0.6h = 85$

Step2: Isolate the term with $h$

Subtract 82 from both sides:
$0.6h = 85 - 82$
$0.6h = 3$

Step3: Solve for $h$

Divide both sides by 0.6:
$h = \frac{3}{0.6}$

Answer:

Equation: $82 + 0.6h = 85$
Solution: $h = 5$
