A racecar, traveling at constant speed, makes one lap around a circular track of radius r in a time t . Which one of the following statements concerning this car is true ?

A train(T) is running uniformly on a straight track. A car is travelling with constant speed along section AB of the road which is parallel to the rails. The driver of the car notices that the train is having a speed of 7 m//s with respect to him. The car maintains the speed but takes a right turn at B and travels along BC. Now the driver of the car finds that the speed of train relative of him is 13 m//s . Find the possible speeds of the car.
