Answer:
t = 150 [s]
Explanation:
To solve this problem we must take into account that the car travels at a constant speed, that is, there is no acceleration or it is equal to zero, therefore we can use the following equation of kinematics.
X = Xo + (v*t)
where:
x = final point [m]
Xo = initial point [m]
v = constant velocity = 20 [m/s]
t = time [s]
X - Xo = the distance traveled = 3000 [m]
3000 = 20*t
t = 150 [s]
