1km = 1000m
1h = 3600sec
Length = speed/time.
S = 1000/3600 = 5/18.
6 * 5/18 = 16.66667.
16.66667m/sec * 9 = 150m.
1h = 3600sec
Length = speed/time.
S = 1000/3600 = 5/18.
6 * 5/18 = 16.66667.
16.66667m/sec * 9 = 150m.

It calculates as 600m->36 sec.
Then X->9sec.
By cross multiplication x =150m.
Then X->9sec.
By cross multiplication x =150m.

Speed = 60 km/hr = 16.67 m/s.
Distance = Speed × Time = 16.67 × 9 = 150 m.
Distance = Speed × Time = 16.67 × 9 = 150 m.
