Answer:
The temperature at 6 P.M. is -14°C
Step-by-step explanation:
The temperature at 4 P.M. = -8 degrees Celsius
The duration over which the temperature decreases by 3 degrees = 2 hours
The total decrease in temperature = 2 × 3 = -6°C
There the temperature change after 2 hours = -8°C -6°C = -14°C
The time change after 2 hours = 4 P.M. + 2 hours = 6 P.M.
Therefore, the temperature time after 2 hours = 6 P.M.
Which gives;
The temperature at 6 P.M. = -14°C.
