Convert km to m - 60000.
Convert hr to sec - 3600.
Sso, 60000/3600 = 16.666(speed) * 9 (time) = 150.

1 km = 1000 m,
1 hours= 60 min.
60km=6 hours that 1km=1 hours,
1000/60*9=150,
So, D. 150 is correct.
1 hours= 60 min.
60km=6 hours that 1km=1 hours,
1000/60*9=150,
So, D. 150 is correct.

Speed = 60 km/h = 60 * 5/18 = 50/3 m/s.
Time taken = 9 sec.
Length = speed * time = 50/3 * 9 =150 m.
Time taken = 9 sec.
Length = speed * time = 50/3 * 9 =150 m.

60 km/3600 sec = 0.016667.
0.016667 km/sec*9 sec = 0.15 sec.
0.15 sec*1000 meter = 150 meter.
0.016667 km/sec*9 sec = 0.15 sec.
0.15 sec*1000 meter = 150 meter.
