How fast would travel at 0.9 c be?
Like, how long would it take (on average) for a spacecraft going 0.9 c to get from Earth to Mars, or from Earth to Jupiter?

Jesus Christ op
Distance (Earth to mars) =112 million km
Speed (0.9c) = 270,000km/s
Time = distance/speed = 414s or 6min 54s

Relativistic effects arent even big enough to be called a rounding error at 0.9c
You need to start hitting 0.99c

Wrong. At 0.9c, time on board the craft should pass at about 43% of the rate it would for the observer.

you can not do this, it's a short distance, acceleration would crush you and your ship, hitting a rain of sand on your way would crush you and your ship, also you would need an insane amount of energy

bottom line, you don't travel this fast within the solar system
