Question

The temperature of a city is 10°C. Due to cold winds, it begins to drop at a rate of 4°C per hour. How long will it take for the temperature to fall to −2°C?

Answer 1

Answer:

4 hours

Step-by-step explanation:

Temperature is decreasing at a constant rate of 4°C per hour

So to fall by 16°C it would require 4 hours as in one hour it falls by 4

So for 16 ( ie 4×4) it would require 4 hours
