Answer:
Would take 1.48 x 10¹¹ years to cross the galaxy
Step-by-step explanation:
galaxy is estimated to be 5.6 × 10¹⁹ mi across = Distance
spaceship traveling at 43,000 mph = Speed
From Speed = Distance / Time
∴ Time = Distance / Speed
= 5.6 × 10¹⁹ / 43,000
= 5.6 × 10¹⁹ / 4.3 x 10⁴
= 5.6/4.3 x 10¹⁹ ⁻ ⁴
= 1.3 x 10¹⁵ hours
Convert time in hours to years
Asuming 24 hours make a day and 365days make a year
= 1.48 x 10¹¹ years to cross the galaxy
