Question

What is the temperature when-4C degrees by 7

Answer 1

Answer:

present temperature = (-4)°c

rate of increasing in temperature =2°c/hours

Midnight=12.00am

4.00am - 12.00am = 4hours

in 4 hours increase of temperature

=(4x2)°c

=8°c CEO at 4 a.m. temperature be

= {(-4)+8}°c

=4°c

again

12 p.m. - 12 a.m. = 12 hours

temperature increasing in 12 hours

=(12x2)°c

=24°c

hence temperature at 12 p.m. be

=(-4+24)°c

= 20°c
