Question

From midnight to 2:00 am, the temperature rose

1.55
1.55°C each hour. If the temperature at midnight was
−
7
−7°C, what was the temperature at 2:00 am?

Answer 1

The answer is -3.9 degrees Celsius because 1.55+1.55=3.10 (We do this because 1h= +1.55 so 2h = +3.10) and then we do -7+3.10= 3.90 degrees Celsius (we do this because we do the initial temperature plus the temperature risen in 2 hours)

Answer 2

-3.90

Explanation:

1) 1.55+1.55 =3.10

2) -7+3.10= (-3.90)
