A bus leaves a bus stop and accelerates at a constant rate for 10 seconds. During this time, the bus traveled 20 meters. Then the bus traveled at a constant speed for 10 seconds. Then the driver noticed his destination 10 meters ahead and slams on the brakes. Assume the bus decelerates at a constant rate. Eight seconds after the bus left the bus stop, a car passed by the bus stop travelling with constant velocity of 10 meters per second. How long (from the bus stop) will the car meet the bus? Express your answer in "seconds"
