the swing of a pendulum gradually decreases with time . however , even then it is regarded as a reliable time keeping device1.Rajdhani express takes 3 hrs to cover 315 km. Shatabdi express takes 6 hours to cover the distance of 600 km. Find the speed of both the express trains. Which express train will cover the distance of 400 km in less time?
2.The odometer of can reads 10532.0 km at the start of journey and at end it reads 10850.0 km. If car takes 12 hour to complete its journey. Then calculate its average speed in km/hr, km/min and km/s.
