Respuesta :
If a train travels 50 kilometers in 4 hours, and then 74 kilometers in 2 hours its average speed is 24.75 km / hr.
Explanation:
Speed is related to the ratio of distance and time. Speed = Distance / time.
Speed of the first train = 50 / 4 = 12.5 km / hr
Speed of the second train = 74 / 2 = 3 7 km / hr
Average speed = (12.5 + 3 7 ) / 2 = 24.75 km / hr
So the average speed of the train is 24.75 km / hr.
