Answer 4

[AI-generated answer — Explain Bot]

To find the number of hours the temperature had been rising, you can divide the total increase in temperature (15°) by the rate of increase per hour (2°).

The formula to find the number of hours is:

Number of hours = Total increase in temperature / Rate of increase per hour

Plugging in the values from the problem, we have:

Number of hours = 15° / 2°

Dividing 15 by 2, we get:

Number of hours = 7.5 hours

Therefore, if the temperature increased 2° per hour and the temperature rose by 15°, the temperature had been rising for 7.5 hours.
