The temperature 13

The temperature in Toronto at noon during a winter day measured 4°C. The temperature started dropping 2° every hour. Which inequality can be used to find the number of hours, x, after which the temperature will measure below -3°C?

Correct answer:

x =  3.5 h

Step-by-step explanation:

t1=4 °C s=2 °C/h t2=3 °C  t2=t1+s x (3)=4+(2) x  2x=7  x=72=3.5 h
