Question 1173862: A car travels at a velocity of 120 km/h and passes a bicycle traveling at a velocity of 15 km/h. From the point of view of a rider on the bicycle, what is the velocity of the car? (Assuming both vehicles are travelling on a straight path)
Answer by math_helper(2461) (Show Source): You can put this solution on YOUR website!
The answer depends on whether they are traveling in the same direction or opposing directions:
120km/hr - 15km/hr = 105km/hr if they are traveling in the same direction
120km/hr + 15km/hr = 135km/hr if they are traveling in opposite directions
The problem should give the numbers as "speeds," not "velocities." Why? because velocity requires magnitude AND direction, and no direction was given.
