your friend just challenged you to a race. you know in order to beat him, you must run 15 meters within 20 seconds in a northern direction. what does your average velocity need to be to win the race? (2 points) .5 meters per second, north .75 meters per second, north 1.3 meters per second, north 300 meters per second, north
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
