A pitcher of water at 40 degrees Fahrenheit is placed into a 70 degree room. One hour later, the temperature has risen to 45 deg

Inessa [12570]

Answer:

3 hours

Step-by-step explanation:

The temperature change after an hour shows an increase of 5 degrees. To calculate how long it takes to reach 60 degrees, we first find the difference from the current temperature to 60 degrees.

60 - 45 = 15 degrees

Since a rise of 5 degrees occurs in one hour, we divide 15 by 5 to find out how many hours are needed to reach 60 degrees.

15 / 5 = 3 hours
