(b) At what time would the temperature of Shyamnagar be 10 °C below zero?
(c) What would be the temperature of Shyamnagar at mid-night?
(d) Here, which value is depicted?​

Answer 1

Answer:

a) at 5 pm(evening)

b)at 3 am(morning)

c) -7

Step-by-step explaination:

a) temperature at 12 noon= +5

temperature decreases at the rate of 1 per hour

this implies that the temperature would be 0 after 5 hours from 12 noon

time at 5 hours after 12 noon = 5 pm(evening)

b)the temperature would be 10 below 0, 10 hours after 5pm as it was 0 at 5 pm

time at 5 hours after 5pm= 3am(morning)

c)temperature at 12 midnight would be 12 less than the temperature at 12 noon ( as the time difference between 12 noon and 12 midnight is 12 hours)

that is  5-12= -7

therefore temperature at 12 midnight is -7

d) the helpful nature of the neighbours is depicted here
