Question

Ricardo measured the temperature in the morning. The temperature was -6 °C. The temperature is increasing 11 °C every hour. After how many hours will the temperature be at least 2 °C?

​

Answer 1

If the temperature was -6 °C in the morning, and it is increasing by 11 °C every hour, it will be at least 2 °C after (-6 - 2) / 11 = <<(-6-2)/11=0.45>>0.45 hours.

Since the temperature is measured in hours, and a fraction of an hour cannot be measured, the temperature will be at least 2 °C after 1 hour.
