(c) One to and fro motion of a clock pendulum takes time = 2 s. (d) 36 km h -1 = 10 m s -1. WebUsual average speed of the bus = 30 km/h. Time taken by the bus to reach the railway station = 4 hours (from 6 o’clock to 10 o’clock) We know that distance travelled = Average speed × time taken. ∴ Distance covered by the bus = (30 × 4) km = 120 km. On the rainy day, the average speed of the bus = 20 km/h.
