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.

Well,
In my view 36 sec ---- 600 mt.
So, 9 sec ----150 mt.
In my view 36 sec ---- 600 mt.
