Vanda put some water in the freezer. When she removed it, the water’s temperature was 0°C. Leaving it out will raise the temperature 4°F each hour. At this rate, when will the water’s temperature be 52°F?
5 hours.
4 hours.
13 hours.
52 hours.
Detailed Explanation
0°C is equivalent to a Fahrenheit temperature of 0°(9/5)+32= 32° F. To become 52° F, the temperature must rise 20° F. If it rises 4° F every hour, then 20/4 or 5 hours later, it will be at 52° F.
