velocity can be calculated using the following rule:
velocity =distance/time
now, the distance is given 15 meters and the time is 20 seconds.
so, just directly sibstitute in the equation to get the velocity as follows:
velocity = 15/20 = 0.75 m/sec

The right choice is 0.75 m/sec north.
Hi there,

the answer is 0.75 m/sec north.
