Question

The temperature fell 12°F from 46°Fto 34°F in 10 hours. how much would the temperature fall over 15 hours if the pattern continued

Answer 1

18 degrees F because 
it dropped 12 degrees=10 hours
                   x degrees=15 hours
x is what you want to find out which is how many degrees it would drop in 15 hours.
12x15 then divided by 10 is 18.
