1 km = 1000 meter.
and 1 hrs= 3600 sec.
So converting it in mtr/sec= 1000/3600.
So, you will get 5/18.
and 1 hrs= 3600 sec.
So converting it in mtr/sec= 1000/3600.
So, you will get 5/18.

60*5/18 = how to calculate this logic, but I'm clear next step --50/3*9=150---guys please explan this.

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

60km per hour(60 minutes).
1km (1000 meter) per minute (60 second).
So, length= 1000/60 * 9 = 150m.
1km (1000 meter) per minute (60 second).
So, length= 1000/60 * 9 = 150m.

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