Question

The temperature at 5 a.m. was 60C above 0. If the temperature drops at the rate of 30C ever hour, what will be the temperature at 8 a.m.?

Answer 1

Answer:

As 1 hour=30C

so a total of 8-5=3hours

therefore,30×3=90C should be reduced

so 60C-90C= -30C.

Hope this works

Answer 2

Answer:

Given,

At 5 a.m. temperature= 60°C

Rate of temperature dropping every hour= 30°C

Time difference = 8-5= 3 hours

∴ Temperature after 3 hours = 3*30°C= 90°C

∴Temperature at 8 a.m. = 60°C - 90°C= -30°C

Hope it helps you!!  :)
