Question

The temperature on Certain morning is -11°C at 5 am. If the temperature drops 3 degrees by 6am and rises 5 degrees at 8 am and then drops 3 degrees at 9 am. What is the temperature at 9 am? ​

Answer 1

First the temperature was -11°C at 5am

then ut dropped to 3degrees at 6am

it means

-11-3 = -14

so at 6am the temperature was -14°C

then it rises 5degrees at 8am

it means

-14+5 = -9.

so at 8 am the temperature was -9°C

then it drops 3 degrees at 9am

it means

-9-3= -12

so at 9am the temperature was -12°C
