Question

A sauna has an initial temperature of 80° If the opening to the sauna is left open, and the temperature therefore decreases by 3% every minute, what is the temperature of the sauna after 210 seconds?

Answer 1

Answer:

71.6°

Step-by-step explanation:

=210s÷60s(1 minutes)

=3.5mins

=3.5mins×3%(=1min)

=10.5%

=100%-10.5%

=89.5%

=89.5%/100×80°

=71.6°
