My math sucks, Can someone give me a hand

[Digital Packrat]

Im trying to calculate the travel time of my freighters to make sure i can keep my supply's up.
Im sending from a planet 22.662 LYs away.
So i took the distance and divided by my LYs per second which is 0.15 and i got 151.08
So if i did that right the travel time should be around 2 minutes and 31 seconds.

In general my math skills are just horrible so i just wanted to ask.
Thanks

-Be nice if the game would tell you these kinds of things..

Looks about right - although keep in mind that planet distances are not static, as both planets will orbit and add a few AU to that - in the extreme case where both planets' orbits are on the same horizontal plane, and they both have an orbit radius of 10 AU, it can add up to a third of a LY to the distance (in DSP: 1LY <=> 60AU)

Also, the launch and landing also take a set amount of time. Not sure how much planet rotation impacts travel time, e.g. if a vessel approaches a planet from the opposite side of its destination.

Balancing out the routes in the late game is not a trivial problem for sure. It is very easy to put a tower down but what is the vessel/drone throughput? It is not easy to calculate that. For late game builds it is important to be able to quickly estimate the throughput.

You got to take into account that it is two-way trip. I.e. if you are trying to optimize throughput, you need to account for vessels travelling back and forth.

I don't think planet position or rotation will matter much if at all at this kind of estimation. It will affect by a few seconds which is inconsequential.

So say you have 10 vessels carrying 1000 items per trip. I will round up the one way trip to 3 minutes. Your throughput will be around 10*1000/(3*2) = 1666 items/min.

A bit less than a blue belt. Now if you need more that that you can put more towers requesting and supplying the same item. If you have 2 towers you will double that throughput.

So you need to estimate how much of the item you need and add according number of towers and vessels into the "trade route".

Yep assuming the numbers are correct it's a 2.5 min travel time. As mentioned above remember the ships have to do a return trip which doubles the travel time per load.
