Particle movement

Postby Nintendon't » Sat Sep 19, 2009 3:35 pm UTC

A particle moves along the x-axis according to the equation x = 50.0t + 10.0t^2, where x is in meters and t is in seconds. Calculate the average velocity of the particle during the first 2.85 s of its motion.

I am getting 37.5 m/s, but apparently it's wrong. Can anyone help me to get to the right answer?

How are you getting that answer, first of all?
