A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose 1/10 degree every 1/4 hour for a limited time. What was the rate , in degrees per hour that the temperature of the compound rose.

The rate is degree per hour.

Step-by-step explanation:

Given : A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose degree every hour for a limited time.

To find : What was the rate, in degrees per hour that the temperature of the compound rose ?

Solution :

In every hour the temperature of a compound rose degree

To get  the rate, in degrees per hour,

In every 1 hour the temperature of a compound rose is

degree

degree/hr

degree/hr

Therefore, the rate is degree per hour.
