Answer: -9 degrees Fahrenheit
Step-by-step explanation:
Given: Temperature at 6:00 AM = -12 degrees Fahrenheit
Temperature increased each hour =
degrees Fahrenheit
Temperature increase in 6 hours = 
Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours
= -12+3 degrees Fahrenheit
= -9 degrees Fahrenheit
Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit
Reshma's age = x
Reshma = x + 5
Reshma's father= 3x + 5
x + 5 + 3x + 5 = 70
4x + 10 = 70
4 x = 60
x = 15
So Reshma's age currently is 15 and 3(15), which is 45, is her father's age.
