Question

1. The temperature in Lafayette , Louisiana is 5°C at 5 am in the morning. If the temperature keeps

on decreasing by 3°C every hour, what will be the temperature in Lafayette by 4 pm at night?

Answer 1

-28° C

Explanation:

First, find how many hours are between 5 am and 4 pm:

This will be 11 hours

Then, multiply 11 by -3 since it decreases by 3 each hour:

11(-3)

= -33

Then, subtract 33 from 5

5 - 33

= -28

So, it will be -28° C by 4 pm
