From midnight to 7:00 am, the temperature rose 1.1 C each hour. If the temperature at 7:00 am was -0.3 C, what was the temperature at midnight?

Sagot :

The temperature at midnight is -8°C.

How to calculate the temperature?

Let the initial temperature be x.

It should be noted that there are 7 hours between midnight and 7am.

Therefore, the equation will be:

x + (1.1 × 7) = -0.3

x + 7.7 = - 0.3

x = -0.3 - 7.7

x = -8

The temperature at midnight is -8°C.
