If the car is going at constant speed than the velocity isnt changing, only the direction of velocity.
The mean of the velocities.
(finalVelocity + initialVelocity)/2
The formula for Fahrenheit and Celsius conversion is
T(°F)<span> = </span>T(°C)<span> × 1.8 + 32
where T is temperature in F or C ( Fahrenheit or Celsius whatever is the case)
</span>This means that keeping this FORMULA in mind we can add different values to it and accordingly convert values from one to another.
Some examples of fahrenheit conversions to Celsius are :
32°F = 0°C using F = (0 x 1.8) + 32
