Question

For the last 4.5 hours, the temperature has decreased at a rate of 2.8 Degrees Fahrenheit per hour. Which best represents the overall change in temperature over this time period? –12.6 Degrees Fahrenheit –1.6 Degrees Fahrenheit 1.6 Degrees Fahrenheit 12.6 Degrees Fahrenheit?
Please help me!

Answer 1

Answer:

The overall change in temperature over the time period ∆T = -12.6°F

Step-by-step explanation:

Rate of change of temperature r = -2.8°F per hour

Time t = 4.5 hours

The overall change in temperature ∆T = Rate of change of temperature × time period

∆T = r × t

∆T = -2.8°F per hour × 4.5 hours

∆T = -12.6°F

The overall change in temperature over the time period is -12.6°F
