Question

In 5 hours, the temperature steadily fell from 0°F to -25°F. What was the average change in temperature per hour?

Answer 1

• Initial temperature=0°F
• Final temperature=-25°F
• Time=5h

`{\boxed{\sf T_(avg)=(\Delta T)/(\Delta t)}}`

`\\ \sf\longmapsto T_(Avg)=(0-(-25))/(5)`

`\\ \sf\longmapsto T_(Avg)=(25)/(5)`

`\\ \sf\longmapsto T_(Avg)=5°F/h`
