Question

MATHEMATICS EXERCISE 1.1 1. Following number line shows the temperature in degree celsius (°C) at different places on a particular day. Lahulspiti, Srinagar Shimla Bengaluru -10- -5 Ooty + 10 O 5 15. 20 25 ( (b) among the above? What is the temperature difference between the hottest and the coldest places
​

Answer 1

Answer:

no

Step-by-step explanation:

Solution (a):

Bengaluru - 22\degree C22°C

Ooty - 14\degree C14°C

Shimla - 5\degree C5°C

Srinagar - -2\degree C−2°C

Lahulspiti - -8\degree C−8°C

Solution (b):

Hottest place = Bengaluru ( 22\degree C22°C )

Coldest place = Lahulspitu ( -8\degree C−8°C )

So, difference between hottest and coldest part = 22\degree C-\left(-8\degree C\right)22°C−(−8°C)

= 22\degree C+8\degree C\ \ =\ 30\degree C22°C+8°C = 30°C

Solution (c):

Lahulspiti = -8\degree C−8°C

Srinagar = -2\degree C−2°C

Temperature between Lahulspiti and Srinagar = -8\degree C\ -\left(-2\degree C\right)−8°C −(−2°C)

=-8\degree C+2\degree C−8°C+2°C

=-5\degree C−5°C

Solution (d):

Temperature of Srinagar = -2\degree C−2°C

Temperature of shimla = 5\degree C5°C

According to the condition = 5\degree C+\left(-2\degree C\right)\5°C+(−2°C)

=5\degree C-2\degree C\ \ =3\degree C5°C−2°C =3°C

therefore = 3\degree C<5\degree C3°C<5°C

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

Now, temperature of srinagar = -2\degree C−2°C

therefore, 3\degree C>-2\degree C3°C>−2°C

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