Answer 1

Answer:

• At 9 P.M, temperature will be 8°C below 0.
• At midnight, temperature will be 14°C below 0.

Firstly, Temperature at Midnight will be

= 12x2 = 24°C less that 10°C

= 14°C below 0

Secondly, Time at which temperature would be -8

= Which means 18°C should be deducted from 10°C

= 18/2 = 9

which means 9 more hours

Therefore, it's 9 P.M

2pm=8-2=6

3 pm=6-=4

That is how you do it!!!!!
