To make sure that both spheres move the same distance per frame, you can adjust the speed1 and speed2 calculations to use the larger of dist1 and dist2 instead of computing the speeds independently based on each distance.
Here's the modified code:
python
With this modification, both spheres should move the same distance per frame, ensuring that they finish their journeys at the same time.
