A train 552 m long is moving on a straight track with a speed of 88.5 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 13.7 km/h.

Assuming constant acceleration, determine how long the train blocked the crossing. Dis- regard the width of the crossing.
