10 and 36 can be divisible by 2. So 5*2/18*2.

Easy to improve our knowledge.
1 hour = 3600 secs.
1 km = 1000 m.
3600/1000 = 36/10 = 5/18.
60*5/18*9 = 150 m.
1 hour = 3600 secs.
1 km = 1000 m.
3600/1000 = 36/10 = 5/18.
60*5/18*9 = 150 m.

1 km = 1000.
1 hr = 3600 s.
Why it is changed into 10/36 and 5/18?
1 hr = 3600 s.
Why it is changed into 10/36 and 5/18?
