Question

Suppose, the temperature in Moscow was –8°C at 10 AM on 6 December. Twenty-four hours later, it was 12°C higher. What was the temperature at 10 AM on 7 December?

Answer 1

Temperature at 10 AM on 6 december =  –8°C
rise in temperature in 24 hours = 12°C

So temperature at 10 AM on 7 december =  –8°C + 12°C = 4°C

Answer 2

Temperature at 10 am on 6 december=-8d cencius

rise in temperture in 24h=12d cencius

= -8d cencius+12d=4d
