Homework Help: Avg Velocity Avg speed question

  1. Sep 4, 2012 #1
    During a hard sneeze, your eyes might shut for 0.50 s. If you are driving a car at 90 km/h during such a sneeze, how far does the car move during that time.

    Here is where I am having problems. I am not sure what I should be doing. So I was hoping someone could get me started. Is this an avg speed or an avg velocity question? Please give me some tips on how to figure out what these kind of equations are asking of me. For some reason I am having trouble starting.

    This seems like a conversion question...

    The car is moving at constant velocity and constant speed. The distance it travels in a time t and at a constant speed v is given by a simple equation. But yes, first you need to convert the speed to a compatible unit (like m/s) to be consistent with the unit of time which is given in seconds.

    Sorry I answered. You got it right.
