How fast were you traveling?

Question

Suppose you were able to drive 300 kilometers in 6.0 hours at a constant speed. a) How fast were you traveling precisely 4.0 hours into your trip? b) Where were you located precisely 4.0 hours into your trip? 

Answer 1

Well, if you were traveling at a constant speed of 50km/hour (300km/6hrs) from start to finish, then you should be going 50km/hr four hours into your trip.  In four hours, you would have traveled 200 km towards your destination.
