Ex. 1.1 Q.1

Following number line shows the temperature in degree Celsius (⁰C) at different places on a particular day:

(a) Observe this number line and write the temperature of the places marked on it.

(b) What is the temperature difference between the hottest and the coldest places among the above?

(d) 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) The temperature of the places marked on it is:

Places Temperature Places Temperature

Bangalore 22⁰C Srinagar –2⁰ C

Ooty 14⁰ C Lahulspiti –8⁰ C

Shimla 5⁰ C

(b) The temperature of the hottest place Bangalore = 22⁰ C

The temperature of the coldest place Lahulspiti = –8⁰ C

Difference = 22⁰ C – (–8⁰ C) = 22⁰ C + 8⁰ C = 30⁰ C

The temperature of Lahulspiti = –8⁰ C

Difference = –2⁰ C - (–8⁰ C) = –2⁰ C + 8⁰ C = 6⁰ C

(d) The temperature of Srinagar and Shimla = 5⁰ C + (–2⁰ C) = 5⁰ C – 2⁰ C = 3⁰ C

The temperature at Shimla = 5⁰ C

Therefore, 3⁰ C < 5⁰ C

Thus, temperature of Srinagar and Shimla taken together is less than the temperature at Shimla.

Now, Temperature of Srinagar = –2⁰ C

Therefore, 3⁰ C > –2⁰ C

No, it is not less than the temperature at Srinagar.
