A cross-country skier travels 40 meters north in 2 minutes. What is the skiers velocity?

v = 0.33 [m/s]

Explanation:

We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.

where:

v = velocity [m/s]

d = displacement = 40 [m]

t = 2 [min] = 120 [s]

Now replacing we have:

d is the answer i came up with

b.transmitters send radio waves, and receivers capture radio waves.
