You travel a distance of 500 kilometers in 10 hours. What is your average speed in kilometers per hour?

Answer 1

Always be careful when answering questions like this because "average speed" is calculated differently from "average velocity".  In this case you're being asked for "average speed".   Average Speed is calculated by dividing ALL the distance by ALL the time.  In this case the solution is very straightforward:  divide the given distance by the given time.  Some other examples might be trickier - just remember:  For average velocity, always divide ALL the distance by ALL the time.
