Answer:
Average rate of temperature increase is 2 degrees per hour
Step-by-step explanation:
Here, we want to calculate the average rate of increase in temperature
From what we have above, we can calculate this by dividing the total temperature rise by the number of hours
The total temperature rise is 6 + 4 = 10 degrees
This means that the temperature rose by 10 degrees between 10 am and 3 pm
The number of hours between 10 am and 3 pm is 5 hours
So the average rate of temperature increase is 10 degrees/ 5 hours = 2 degree per hour
