Given parameters:

Initial speed of train  = 0m/s

Final speed  = 25m/s

time = 20s

Unknown:

Total distance covered  = ?

Solution:

Speed is a scalar quantity that has magnitude and no direction.

Mathematically;

     Speed  = [tex]\frac{distance}{time}[/tex]

  distance  = speed x time

 Input the parameters and solve for distance;

    Distance  = 25 x 20 = 500m

The distance covered is 500m
