Question

9. How many times did the temperature rise one degree per hour?

A none
B 1
C 2
D 3

Answer 1

A - none

This is because the closest it gets to one degree per hour is not rising, rather, it lowers one degree from three to four.

Hope this helps!

Answer 2

From noon to 1 pm:

The temperature rose from 75 to 77, so it rose 2 degrees.

From 1 pm to 2 pm:

The temperature remained constant at 75 degrees.

From 2 pm to 3 pm:

The temperature rose from 77 to 79, so it rose 2 degrees.

From 3 pm to 4 pm:

The temperature decreased from 79 to 78, so it decreased 1 degree.

From 4 pm to 5 pm:

The temperature rose from 78 to 81, so it rose 3 degrees.

So, the answer is "none"
