Convert 64km.h^-1 to meters per second (m.s^-1)???

To convert from kilometers per hour (km/h) to meters per second (m/s), you can use the following conversion factor:

1 km/h = 1000 m / 3600 s

So, to convert 64 km/h to m/s:

64 km/h * (1000 m / 3600 s) = 17.7778 m/s

Therefore, 64 km/h is equal to 17.7778 m/s.

1 km = 1000 m

1 h = 3600 s

So, 64 km.h^-1 = 64 - 1000 m / 3600 s = 17.78 m.s^-1 (approximately)
