Question

The temperature of place A at midnight was 4°C below zero if it increases at the rate of 2°C per hour what was the temperature at 4 am​

Answer 1

Answer:

4°C

Step-by-step explanation:

at midnight temp is => -4°c

rate of changing temp => 2°c / hr

at 2am temp will be => -4°c + ( 2°c X no. of hr )

No. of hr = 2

hence, at 2am temp will be = -4+4

= 0

at midnight temp is => -4°c + ( 2°c X 4 )

= -4°c + ( 8 )

= +4°c
