Question

दोपहर 12:00 बजे तापमान शून्य से 10 डिग्री सेल्सियस ऊपर था यदि या 24:00 तक 2 डिग्री सेल्सियस प्रति घंटे की दर से कम होता है तो किस समय तापमान शून्य से 8 डिग्री सेल्सियस नीचे होगा रात के 12:00 बजे तापमान क्या होगा​

Answer 1

Answer:

-8°C at 9:00 pm,-14°C at 12:00 am

Step-by-step explanation:

-8 is 18°C lower than 10°C

Then, time taken = 18/2

time taken = 9 hours

time on clock = 9 hours after 12 noon,

it will be 9:00 pm

as we know that rate of change of temperature is 2°C per hour

then,at 12:00am

the temperature = 2 *12

the temperature = 24°C lower than 10°C

the temperature = 10 - 24°C

the temperature = -14°C
