Question

The temperatures of 5 cities in India on a particular day are shown on the given number line. Which city has the highest temperature?

Answer 1

Hint:
Here, we’ll be using concepts of the number line. On number line number which is on the left are smaller than the number which is present on the right-hand side.

Complete step by step solution:
We are given five different cities on the number line Kasauli, Manali, Nainital, Ooty and Bangalore.

If you observe the number line, there are numbers on the left and right of zero which is supposed to be at the centre. Numbers on left of the zero on the number line are negative. Whereas numbers on the right of the zero on the number line are positive.
Now in case of this figure, there are three cities on the left side and two on the right side.
When the temperature is measured, we know that,
The most negative or minimum temperature is, the coldest the place is.
The most positive or maximum temperature is, the hottest the place is.
Now let’s list out the cities with their temperature.

Name of the city	Temperature
1.kasauli	$-9^{\circ}$
2.manali	$-7^{\circ}$
3.nainital	$-3^{\circ}$
4.ooty	$15^{\circ}$
5.banglore	$20^{\circ}$

From the table, we can see the city with the highest temperature is Bangalore.

Note:
The number line is a way to visualise all the known numbers on a line. on moving left to right on the number line the numbers increases and on moving right to left numbers decreases.
