If a planet was 5 million light years away from earth, the James Webb from earth would see it as it was 5 million years ago.
And say if we continued to watch this planet from the earth we would see events happening at the same speed on earth.
if I was to fly towards this planet in a space ship with a telescope, would I see events on the planet being sped up and if I was to fly away would events happen in slow motion?

Effectively, yes. This is an example of the [doppler effect](https://en.wikipedia.org/wiki/Doppler_effect) which you can observe here on Earth with sound waves.
An important thing to note is that this is not the same thing as time dilation. Sometimes people get these two things confused, but they’re completely separate effects.
