Hi there!
We can use the kinematic equation:

vf = Final velocity (? m/s)
vi = initial velocity (0 m/s, dropped from rest)
a = acceleration (due to gravity, 9.8 m/s²)
d = distance (9.8 m)
Simplify the equation to solve for vf:

Substitute in the given values:

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.
