Traveling 50,000 mph, how long would it take to travel 17.4 light-years?

The first step is to convert the speed from mph to m/s.

1 mph * 5280 ft/mi * 12 in/ft * 2.54 cm/in * 1 m/100 cm * 1 h/3600 s = 0.44704 m/s/

v = 50,000 * 0.44704 = 23,352 m/s

One light year is the distance light moves in one year.

d= 17.4 * 365.25 days/year * 24 hr/day * 60 min/hr * 60 s/min = 5.4910224 * 10^8 meters

t = 5.4910224 * 10^8 ÷ 23,352

The time is approximately 23,514 seconds. One hour is 3,600 seconds.

t = (5.4910224 * 10^8 ÷ 23,352) ÷ 3,600

The time is approximately 6.53 hours. I hope this is helpful for you.
