Question

*3 Starting from rest, a car travels for 2 minutes with
a uniform acceleration of 0.3 m s^-2, after which the
speed is kept constant until the car is brought to
rest with a uniform retardation of 0.6 m s^-2. If the
total distance covered is 4500 m, what is the time
taken for the journey?​
