Question

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. If it continues to fall at this rate, find each indicated temperature.

Answer 1

-6°C

-15°C

-1.5°C

Explanation:

The computation is shown below:

in one hour the temperature falls by 3°C i.e.

= 0 - 3

= -3°C

In two hours

= 2 × - 3°C

= -6°C

In five hours

= 5 × -3°C

= -15°C

in half an hour

= 0.5 × -3°C

= -1.5°C
