mid- night was 48% below zero.

2°c per hour, what was the
temperature a 4 a.m.?




​

Answer 1

Answer:

-40°C

Step-by-step explanation:

midnight means 12am.

48% below 0°C means -48°C.

so from 12am to 4am its 4 hours.

and the temperature increases (becomes hotter) by 2°C every hour.

therefore, 4×2 = 8°C increase from -48°C to -40°C.
