B. Marie heated water in a beaker. When she began, the water had a
emperature of 40 degrees Fahrenheit and she heated it at a rate of 2.5
degrees Fahrenheit per minute. Kathy heated water in a different beaker.
When she began, the water had a temperature of 50 degrees Fahrenheit
and she heated it at a rate of 1.5 degrees per minute. Which equation
could be used to determine how many minutes passed before the water
cemperature in both beakers was he same? *
