Camila conducted a scientific experiment. For a certain time, the temperature of a compound rose 1 1/2 degrees every 3/4 of an hour. What was the rate, in degrees per hour, that the temperature of the compound rose?

First, let's convert the mixed fraction given for the degrees that the compound rose into a fraction:


1(1)/(2)\rightarrow(2+1)/(2)\rightarrow(3)/(2)

Therefore, the compound's temperature rose 3/2 degees.

In order to get the rate, divide the degrees that the compound's temperature rose by the time elapsed. In this case, 3/4 hours:


((3)/(2)degrees)/((3)/(4)hours)\Rightarrow(12degrees)/(6hours)\Rightarrow2\text{ degrees per hour}

This way, the rate is 2 degrees per hour
