Rate 3

A liquid is heated at a rate of 5 degrees Celsius per minute. If the temperature now is at 39 degrees Celsius, after how long will the temperature be 94 degrees Celsius?

Result

t =  11 min

Solution:

$t_{2}=94 \ ^\circ \text{C} \ \\ t_{1}=39 \ ^\circ \text{C} \ \\ s=5 \ ^\circ \text{C/min} \ \\ t=\dfrac{ 94-39 }{ 5 }=11 \ \text{min}$
