The temperature at noon is 0°C. The temperature changes buy-3/2°C every hour for 4 hours. Write a expression to represent this situation. What is the temperature at 4:00pm?

So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is - 3/2°c

T = To + (-3/2°c) x

Where x is the fraction of 4 in hours

Step-by-step explanation:

Its a very simple Expression.

First we consider the first temperature at first time which is 0°c at 12 noon which I initial time, i. e t = 0.

For every four hour change, the temperature adds - 3/2°c.

So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is - 3/2°c

The expression to know the temperature is

T = To + (-3/2°c) x

Where x is the fraction of 4 in hours
