Hello Orion's Arm, my name is Dan Saranich. I'm 17 years old, from Connecticut (United States), and have a penchant for hard science fiction and space travel. I've been reading for almost a year now and I love some of your content, though disagree on certain things.

I have a question that I wanted a serious answer to.

When calculating the travel time for a spacecraft going from Planet A to Planet B, should I divide the spacecraft's exhaust velocity by the distance between points.

For Example, a spacecraft going from Earth to Mars with an exhaust velocity of 11,000,000 m/s. The mean distance between Earth and Mars is 1.7 AU (254,000,00 km).

1.7 AU / 11,000,000 m/s

= 6 Hours, 25 Minutes.

Is this the correct way to calculate how long a hypothetical flight would take place? Just wanted to know.

Thanks!
