Question

A certain freezing process requires that room temperature be lowered from 380C at the rate of 50C every hour.What will be the room temperature 5 hours after the process begins?

Answer 1

Answer:

130°C

Step-by-step explanation:

Current room temperature = 380°C

rate of lowering of temperature= -50°per hour
