Question

A certain freezing process requires that room
temperature be lowered from 30°c at the
rate of 6°c every
hour What will be the room
temperature 12 hours after the process begins?​

Answer 1

Answer:

42°c

Step-by-step explanation:

Room temperature at the start of the process= 30°C

Rate of decrease every hour= 6°c

Room temperature after 12 hours= ?

30-6= 24

24-6= 18

18-6= 12

12-6= 6

6-6= 0

0-6= (-6)

(-6) - 6= -12

(-12) - 6= -18

(-18) - 6 = -24

(-24) - 6= -30

(-30) - 6= -36

(-36) - 6= -42

Therefore the temperature of the room will be 42°c after 12 hours
