The 6am temperature in one of the coldest cities in europe is 0degrees .The noon reading is 12 degrees celsius higher than this, but by midnight the temperature has fallen to 11 degrees celsuis below the noon reading .By how many degrees celsuis has the temperature fallen between 6am and midnight?

-11°c

Step-by-step explanation:

6am temperature= 0°

6 am temperature is 0°

12pm temperature= 12° + 0° = 12°

Noon temperature is said to be 12° higher than the temperature by 6 am so we add the temperature at 6 am and the temperature at noon ( 12pm)

Midnight temperature= 12° - 11°= 1°

By midnight, the temperature has fallen below the temperature at noon by 11° so we subtract the temperature at 12pm (noon) which was 12° by 11°

So we want to find out how many degree Celsius has the temperature fallen between 6 am and midnight,

Recall that by 12pm (noon) the temperature increased, not decreased, so we ignore the temperature at 12pm

By midnight, it has fallen by 11° which is negative 11° (-11°)

Therefore, between 6 am and midnight, the temperature fall was - 11°c

whatvare the choices
