Formula.
1. Distance = speed * time
2. km/hr --> m/sec conversion
For ex. convert 90 km/hr to m/sec
Solution:-
90 km/1 hr = 90,000 m/3600 sec
= 25 m/sec.
1. Distance = speed * time
2. km/hr --> m/sec conversion
For ex. convert 90 km/hr to m/sec
Solution:-
90 km/1 hr = 90,000 m/3600 sec
= 25 m/sec.

You can simply solve like this.
1 0mtrs/1hr * second.
1000/60 * 9 = 150.
1 0mtrs/1hr * second.
1000/60 * 9 = 150.
