Speed = total distance /time = 51/3 =17 km /h
30 min = 1/2 hour
Distance = speed × time = 17 ×1/2 =8.5 km

1hour=60min so, 3 hour = 3×60=180min
Train covers in 180min =51 km
Train cover in 1 min = 51/180
Train covers in 30 min = 51/180×30 = 8.5 km
Then
Speed = d/t = 51km/3hour= 13.66km/hour
Train covers in 180min =51 km
Train cover in 1 min = 51/180
Train covers in 30 min = 51/180×30 = 8.5 km
Then
Speed = d/t = 51km/3hour= 13.66km/hour
