Following number line shows the temperature in degree Celsius $(°\mathrm{C})$ at different places on a particular day. Observe this number line and write the temperature of the places marked on it.

Following number line shows the temperature in degree Celsius $(°\mathrm{C})$ at different places on a particular day.  If the temperature difference between the hottest and the coldest places among the marked cities is $\mathrm{T}°\mathrm{C}$, then find the value of $\mathrm{T}$.

Following number line shows the temperature $\left(°C\right)$ at different places on a particular day. If the temperature difference between Lahulspiti and Srinagar is $T°\mathrm{C}$, find the value of $T$.

Following number line shows the temperature in degree Celsius $(°\mathrm{C})$ at different places on a particular day. Can we say temperature of Srinagar and Shimla taken together is less than the temperature at Shimla? Is it also less than the temperature at Srinagar?

A plane is flying at the height of $5000 \mathrm{m}$ above the sea level. At a particular point, it is exactly above a submarine floating $1200 \mathrm{m}$ below the sea level. What is the vertical distance between them?

Rita goes $20$ $\mathrm{km}$ towards east from a point A to the point B. From B, she moves $30$ $\mathrm{km}$ towards west along the same road. If the distance towards east is represented by a positive integer then, how will you represent the distance travelled towards west? By which integer will you represent her final position from A?
