A starship is cruising the interstellar space with a velocity of 2174.799173 miles per second. How far would the starship have traveled in 2 years, 9 days and 4.50 hours? Consider 365 days in one year.

1.3889 x 10¹¹ miles.

Explanation:

2 Years = 2 x 365 days = 730 days

2 years and 9 days = 739 days.

739 days = 739 x 24 = 17736 hours

2 years 9 days and 4.5 hours = 17736 + 4.5 = 17740.5 hours

17740.5 hours = 17740.5 x 60 x 60 = 63.865 x 10⁶ s

Distance travelled = velocity x time

2174.799173 x 63.865 x 10⁶ = 1.3889 x 10¹¹ miles.
