Question

When 2 cars pass each other going opposite ways at 50mph,Is the speed they pass each other at 50mph or 100mph?

Answer 1

if your are inside one of the cars, i would seem like to be going 100mph. but relatively, the speed that they are passing each other is only 50mph.

Answer 2

they converge, pass and diverge at 100 MPH

it's all about where you are viewing it from - if inside one of the cars the apparent passing speed is 100MPH, whereas someone standing by the side of the road will see them pass at 50MPH

It's all about relativity - you could always read up on Einstein's Theory of Relativity.

Answer 3

They pass each other at 50 but if they crashed head on it would be an impact speed of 100.
