Answer: [tex]\dfrac{3}{5}^{\circ}\ F[/tex]
Step-by-step explanation:
We know that in integers , we use minus (-) sign to show decrease , fall or loss and no sign to plus (+) sign to show increase , rise or profit.
Given : The temperature is increasing steadily at a rate of 3°F every five hours.
i.e. Change in every 5 hours = 3°F
By Unitary method , change in every 1 hour = [tex]\dfrac{3}{5}^{\circ}\ F[/tex]
Since, temperature is increasing , so the temperature change each hour is written as [tex]\dfrac{3}{5}^{\circ}\ F[/tex] [without any sign]
