Two cars, A and B, are travelling clockwise at constant speeds around the track shown in Fig. 16.1.

The track consists of two straight parallel sections each of length 200 m, the ends being joined by semi-circular sections of diameter 80 m.

The speed of A is 20 ms⁻¹ and that of B is 23 ms⁻¹.

Calculate the time for A to complete one lap of the track in seconds.
