Answer:
condition in first train
as we know that speed =distance/time
than distance=speed×time
=48×50/60
distance=40km

speed =distance /time
according to question second train covers same distance as first train which is 40km found above
speed is =40×6/7
speed of second train =34.26km/h approximately
