Question

at sunrise the temperature was-15 ​

Answer 1

Answer:

yes, at sunrise the temperature was-15

Answer 2

Answer:

-15*c

Step-by-step explanation:

since , at the morning the temperature was -15*c and by the midday the temperature increased by 45* c , i.e.( -15) *c + 45* c = 30 *c

therefore, the temperature during the mid day was 30*c .

by the evening the temperature fell to 1/3 rd of the existing temperatue . i.e 1/3 of 30* c

there fore , the temperature in the evening fell to 10 * c

and by the night the temperature decreased by another 25 degrees , thus ,10*- 25 * c = - 15 *c

therefore , the temperature at night was - 15* c
