| The speed of the cyclist is 12 m / s, and the speed of the motorcyclist is 54 km / h, which of them is moving faster, by how much?
Given:
v1 = 12 m / s – speed of the cyclist;
v2 = 54 km / h – the speed of the motorcyclist.
It is required to compare the speeds v1 and v2.
For comparison, let’s translate the speed of a motorcyclist from km / h to m / s:
v2 = 54 * 1000/3600 = 15 m / s.
v2 – v1 = 15 – 12 = 3 m / s.
Answer: the motorcyclist’s speed is 3 m / s higher.
