When we convert 25 m/sec into km/ hour we get 90 km/hour so the difference in their speeds would be
90-72=18 km/hour.. or 5 m/sec (18 km/hour converted in m/sec )jeevan ambati

If the speed of B is converted in Km/hour it would be 80 km/hour... so the difference would be 80-72=8 km/hour or 8 km/hour
