Which speed is greater: 90 km / h or 22.5 m / s? which of the two bodies is moving at a lower speed, expressed in different units.
Given:
v1 = 90 kilometers per hour;
v2 = 22.5 meters per second.
It is required to determine which of the indicated speeds is higher.
In order to compare the speeds, you need to bring them to the same dimensions, namely “meter per second”.
v1 = 90 km / h * 1000/3600 = 25 meters per second.
v1> v2, since 25> 22.5.
Answer: 90 kilometers per hour is more than 22.5 meters per second, respectively, the second body moves at a lower speed.
