Answer 2

Answer:

(a) By observing the given data, the temperatures of these cities are as follows.

Lahulspiti

:

−8°C

Srinagar

:

−2°C

Shimla

:

5°C

Ooty

:

14°C

Bangalore

:

22°C

(b) Temperature at the hottest place, i.e., Bangalore = 22°C

Temperature at the coldest place, i.e., Lahulspiti = −8°C

Temperature difference = 22°C − (−8°C)

= 30°C

Therefore, the temperature difference between the hottest and the coldest places is 30ºC.

(c) Temperature at Lahulspiti = −8°C

Temperature at Srinagar = −2°C

Temperature difference = −2°C − (−8°C)

= 6°C

Therefore, the temperature difference between Lahulspiti and Srinagar is 6ºC.

(d) Temperature at Srinagar = −2°C

Temperature at Shimla = 5°C

Temperature of Srinagar and Shimla taken together = −2°C + 5°C

= 3°C

3°C < 5°C

3°C < Temperature of Shimla

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

However, 3°C > −2°C

Hence, the temperature of Srinagar and Shimla taken together is not less than the temperature of Srinagar.
