Question

a train moving at a speed of 75 km per hour covers a certain distance in 4.8 hours what should be the speed of the train to cover at the same distance in 3 hours

Answer 1

Speed = 75 km/h Time = 4.8 hrs Distance = speed × time                                            =75 × 4.8                                                      = 360 km                                       Speed = ? Distance = 360 km                               Time = 3hrs Speed = distance / time                                         = 360 / 3                                                     = 120 km/h                                 The speed will be 120 km/h to cover 360 km in 3 hrs .
