Given,
Displacement of the car = 150 km
Velocity of the car = 15.0 km/h
We need to calculate the travel time t
We all know that the formula to calculate velocity is
Velocity = displacement / time
From the above equation,
Time = Displacement / Velocity
Substituting the values in the above equation,
Time = 150 / 15.0 = 10 hours
Therefore, travel time = 10 hours.
