Hi,
I found online a nice (and seemed easy) math problem.
Rocket A travel from Mars to Earth in 200 days
Rocket B travel from Earth to Mars in 150 days, but take off 30 days later
When they cross each other, which one is the closet to the earth ?
So they give a “flat” answer, without giving any explanation on how they reach this conclusion.
What would be your simplest Mathematical solution for this ?
Thanks.

@MrJameGumb@lemmy.world No you were right at first ! the question is
When they cross each other, which one is the closet to the earth ?
So indeed when they cross they are the same point in space (more or less otherwise it’s a collision :) ) so if they are at the same point the are at the same distance to Earth… :)
