A car starts at t=0 with a velocity of 25 m/s. It drives with a constant velocity for 1 minute, then it accelerates with a constant acceleration of 0.5 m/s^2 for 20 seconds, then it continues with a new constant velocity for 1 minute. Draw a graph of the velocity versus time. Calculate the total distance the car travels.
