Answer 2

Answer:

2 AM.

Step-by-step explanation:

Given :- The temperature during day time was up to 56°C and during night it dropped by 45°C every day. The temperature drops at the rate of 9°C per hour and starts dropping from 9 pm.

To Find :- Time at which it will be coldest during night.

Solution :-

During day time it's up to 56°C and at night it drops by 45°C = ( 56 - 45 )°C

                                                                                                     = 11°C

Therefore, the minimum temperature will be 11°C.

The rate of temperature drop = 9°C per hour.

Start time of temperature drop = 9 pm.

We know that 9 × 5 = 45°C.

So, the temperature will be lowest at 5 hours from 9 pm which is ( 9 + 5 ) pm = 2 AM.

Therefore, it will be coldest at 2 AM during night.
