Answer» :-The speed of TRAIN in km/h is 162.1 km/h.The speed of train in m/min is 2701.66m/min.Step-by-step explanation ::To Find :-The speed of train in km/hThe speed of train in m/minSolution :-The speed of train in km/h,Given that,Distance covered = 405.25 kmTime taken = 2.5 hoursTherefore, speed is,As we know that,Speed = Distance ÷ TIME,=> Speed = 405.25 ÷ 2.5=> Speed = 162.1 km/hTherefore, the speed of train in km/h is 162.1 km/h.The speed of train in m/minGiven that,Distance covered by train = 405.25 kmTime taken = 2.5 hours,First, we need to convert kilometres to METRE and HOUR to minutes,405.25km = 405250m2.5 hours = 150 minutesTherefore, speed is,As we know that,Speed = Distance ÷ Time,=> Speed = 405250 ÷ 150=> Speed = 2701.66Therefore, the speed of train in m/min is 2701.66m/min. |
