Final Velocity (v) = 15km/hr
Initial Velocity (u) = 10km/hr
Time = 6 seconds
Acceleration = ?

According to Formula :

Acceleration = v – u / t

Acceleration = 15km – 10km / 6 seconds

Acceleration = 15000m – 10000m / 6 seconds

[we will convert smaller units into bigger units. because in time we have smaller unit and here we cant convert time in hours or minute because it is only 6.]

Acceleration = 5000m / 6 seconds

[ means that we will divide 5000 by 6 . You acn also use cancellation method]

Acceleration = 833.333333
