Question

The temperature T in degrees Celsius of a liquid t minutes after heating is given by the formula T=8√t. When is the temperature 48 degrees celsius?

Answer 1

T=8√t
T=temperature
t=time in minutes.
If T=48, we have to calculate the time.

48=8√t
(48)²=(8√t)²
2304=64t
t=2304 / 64=36

answer: 48 degrees Celsius will be reached in 36 minutes.
