Answer:
man on foot 4 km/h = 1.111 m/s, 7km/h = 1.944 m/s
Rabbit 65 km/h = 18.055
A jet airplane 800 km/h = 222.222 m/s, 900 km/h = 250m/s
sound in air at 0 C 330 m/s = 1188 km/h
moon around the earth 1017 m/s = 3661.2 km/h
sound in water 1420 m/s = 5112 km/h
light in vacuum 3 x 10^8 m/s = 108 x 10^7 km/h
Step-by-step explanation:
When converting from km/h to m/s,
multiply the given value in km/h with 1000/3600, or directly by the fraction 5/18
Now when converting form m/s to km/h do the opposite,
multiply the given value in m/s with 3600/1000.
