60 * 60 = 3600,
1000/3600 = 5/18,
60Km/hr.
1km = 1000m,
1hr = 60min.
1sec = 60sec.
1000/3600 = 5/18,
60Km/hr.
1km = 1000m,
1hr = 60min.
1sec = 60sec.

@Aditya.
15%+55% = 70,
30%?
12750÷ 30 = 425*70 = 29750 + 12750 = 42500ans.
15%+55% = 70,
30%?
12750÷ 30 = 425*70 = 29750 + 12750 = 42500ans.

@Jayath how about -14x/100. I do not understand. Where did you get the number?

Length = time/speed.
= 9sec/60kmhr.
= 0.15km = 150meter.
= 9sec/60kmhr.
= 0.15km = 150meter.

5/18 means 5 meters/18 seconds so 5/18 is the conversion of 1km/h.
Thank you.
