Q1. Karim lives in Srinagar , Kashmir. The table below shows the temperature changes in Srinagar over three hour period.
Time Change in temperature
5 a.m. to 6 a.m. -1.50C
6 a.m. to 7 a.m. -2.60C
7 a.m. to 8 a.m. +10C
Karim noticed that temperature at 5 a.m. was -3.50C . What is the temperature of Kashmir at 8 a.m.
Hint:- Start with temperature at 5 a.m. and add the change in temperature over three hour period to find the temperature at 8 a.m.

Answer 1

given that temp at Srinagar at 5 a.m. is -3.5c and as given that at 6 a.m. temp fell by 1.50c and at 7 a.m. temp fell by -2.6c and at 8 a.m. temp rose by 10 c

there fore temp at 8 a.m. = -3.5 -1.5 - 2.6 + 10 = -7.6 + 10 = 2.4 c

Answer 2

ANSWER:-

-6.6°c

step by step explanation:-

SOL -

= The temperature at 5.a.m = - 3.5°c

= The temperature at 5.a.m to 6.a.m = -3.5°c+(-1.5°c)

= -3.5°c-1.5°c

= -5°c

= The temperature at 6.a.mbto 7.a.m = -5°c + (-2.6°c)

= -5°c-2.6°c

= -7.6°c

= The temperature at 7.a.m 5o 8.a.m = -7.6°c + 1°c

= -6.6°c

:. The temperature at 8.a.m = -6.6°c

Ans = -6.6°c
