Question 11

A car travels on a road beside a train track at a constant 22 km/h. A train is 250 metres long and travels at a constant 17 km/h. From the moment the car passes the rear of the train, it takes M minutes to reach the front. Find M. Assume the car and train move in the same direction; track the same point on the car from the rear to the front of the train, so car length is not included.

**Input:** Enter the integer only, without units.
