A person crosses a 600 meter long street in 5 minutes. What is the speed in Km/hr  Choose the correct option
A) 6.2 km/hr  B) 7.2 km/hr  C) 8.2 km/hr  D) 9.2 km/hr  E) None of these
ExplanaƟon:   Two things to give aƩenƟon on this quesƟon.   First Ɵme is in minutes, we need to change it to seconds to get speed in m/sec, then we need to get the   final answer in km/hr.   So lets solve this.   Speed=DistanceTimeDistance=650meterTime=5   minutes=300secSpeed=600300=2m/sec=&gt;2   ∗   185km/hr=7.2km/hr   Answer:7.2 km/hr
