At 3:00

a.m. the temperature was 13degree below zero. by noon it had risen to 32degree. what was the average hourly increase in temperature?

Answer 1

➡HERE IS YOUR ANSWER⬇

Temperature at 3 am = -13 °C

Temperature at 12 pm = 32 °C

12 pm - 3 am = 9 hours

Temperature increasing

= {32 - (-13)} °C

= 45 °C

So, Temperature increased 45 °C in 9 hours.

Therefore, rate of increase in Temperature

= 45/9 °C/hour

= 5 °C/hour
