At 8:00 am, the temperature in the earth science room was measured to be 62 degrees Fahrenheit. By 12:00 pm, the temperature had risen to 70 degrees Fahrenheit. Calculate the rate of change.

Respuesta :

AL2006

Rate of change = (amount of change) / (time for the change)

Amount of change = (temp at the end) minus (temp at the beginning)

Amount of change = (70°F) minus (62°F) = 8°F

Time for the change = (time at the end) minus (time at the beginning)

Time for the change = (1200 - 0800) = 4 hours

Rate of change = (8°F) / (4 hours)

Rate of change = 2°F  per hour
