it is -12.5°C outside when the temperature starts increasing by 2.5°C each hour. How long will it take for the temperature to reach -5°C?

Respuesta :

Answer: 3 hours

Step-by-step explanation:

The span between -12.5 and -5 is 7.5. Divide that by 2.5 (since that’s the change) and that’ll give you the amount of time it takes.
