Problema Solution
During one day in 1918, the temperature in Granville, North Dakota, began at -33 degrees and rose for 12 hours. The high temperature was about 51 degrees. About how many degrees per hour did the temperature rise?
Answer provided by our tutors
The temperature change in the period of 12 hours was: 51 - (-33) = 51 + 33 = 84 degrees
The temperature change per hour is equal to the change in degrees divided by the time in hours:
84/12 = 7 degrees per hour
The temperature was rising at a rate of 7 degrees per hour.
