Answer:
temperature at midnight is -39 and at 4 pm temperature will be -7
Step-by-step explanation:
temp. at noon - 9°c
decreasing rate - 4°/hr
temp. after some hrs - 7 below 0 = (-7°C)
difference between 9° and -7°
= 9-(-7)
= 9+7
= 16°
the temp. fell down by 16 degrees
time needed for temp to fall 16 degrees- 16÷4
= 4 hrs
4 hrs after 12 noon - 4 pm
no. of hrs from noon till midnight- 12 hrs
decreasing rate of temp - 4 degree/hr
temp fall at midnight (after 12 hrs) - 12*4 = 48degree
= 9 - 48
= -39°C
