Answer:
5 hours
Step-by-step explanation:
Given: the water temperature at the beach started at 82 degrees and it is rising 0.6 degrees each hour
To Find: If the water temperature is now 85 degrees write and solve an equation to find h, the number of hours that have passed
Solution:
Current water temperature at beach
temperature rising rate degrees per hour
let be the hours passed.
water temperature at the beach after hour be
Therefore,
equation for water temperature after is
When water temperature is
therefore it will take to reach temperature
