Question

The temperature of a city rose to 35/2 degree celcius from 12 noon to 4 pm. But from 4 pm to 9 pm it fell by 23/5 degree celcius. Find the thermometer's reading at 9 pm if the initial reading at noon was 55/3 degree celcius.

Answer 1

temperature at noon in degree Celsius
$= \frac{55}{3}$

temperature at 4 pm in degree Celsius
$= \frac{55}{3} + \frac{35}{2}$
$= \frac{215}{6}$
temperature at 9 pm in degree Celsius

$= \frac{215}{6} - \frac{23}{5}$
$= \frac{937}{30}$
