1m = 1/1000km and
1s=1/3600hr.
So 1m/s = 3600/1000 = 18/5km/h.
1s=1/3600hr.
So 1m/s = 3600/1000 = 18/5km/h.

1 km=3000m.
60 km=60000.
1 hr=3600sec,
=(60000/3600)*9,
=150m.
60 km=60000.
1 hr=3600sec,
=(60000/3600)*9,
=150m.

Length = speed * time,
L=60 * 5/18,
= 50/3 * 9,
= 150 meters.
L=60 * 5/18,
= 50/3 * 9,
= 150 meters.

60 * 1000m/3600s = 16.66m/s.
So, distance = 16.66 * 9 = 150m.
So, distance = 16.66 * 9 = 150m.
