dear friend hear is ur answer
total length of the train = 350 m
speed of the train 20km/h
the time taken by the train to cross the station master
time. distance
1hour. 20km
xhour. 0.35km
it is direct variation.
x/y = k
1/20=x/0.35
20x=0.35*1
x=0.35*20 = 7 minutes
total length of the train = 350 m
speed of the train 20km/h
the time taken by the train to cross the station master
