Question

At sunrise, the temperature was –4.8°C. During the day, the temperature rose 6.3°C and then fell 5.6°C.

What was the final temperature? {Note: The C stands for Celsius}

A. -16.7 C

B. -4.1 C

C. 5.5 C

D. 7.1 C

Answer 1

Initial temperature = (-4.8)

Rise = 6.3

So, temp. after rise = -4.8 + 6.3 = 1.5

Again, fall = (-5.6)

So, temp after fall = 1.5 - 5.6 = (-4.1)
