Answer» Initial odometer reading=2000kmFinal odometer reading=2400kmTotal distance= Final distance- Initial distance=2400-200=400kmTotal time=8hAverage speed =? Formula to be used :Average speed= Total Distance/Total time Average speed in Km/hr:Average speed=400/8=50 km/hr Average Speed in m/s:1km/hr=5/18 m/s∴50km/hr=50x5/18=250/18=13.88m/s |
