At 3:00 AM, the temperature was 13°C below zero, but by noon it had risen to 32°C. Therefore, the average hourly increase in temperature was ______?
Explanation
Initial temperature = -13°C
Final temperature = 32°C
Total temperature rise = 32 - (-13)
= 32 + 13
= 45°C
Time elapsed = 9 hours (from 3:00 AM to noon)
Average hourly increase = Total temperature rise / Time elapsed
= 45°C / 9 hours
= 5°C/hour
