Question

The temperature of a freezer is never greater than -2 degrees C. Yesterday the temperature was -10 degrees C, but it increased at a steady rate of 1.5 degrees C per hour. How long in hours and minutes did the temperature increase inside the freezer?

There is 8 deg between -10 and -2

rate=difference/time
time=difference/rate=8/1.5=5 1/3 hour or 5 hours 20 min
Thx @Bobpusrley
