How long would it take to travel 120 trillion miles away traveling at the speed of light?

David Lee: How long would it take to travel 120 trillion miles away traveling at the speed of light?
The answers given are contradictory. Please give me the mathematical formula that calculates the speed of light, distance traveled (d) and how long it will take to travel (t) 120 trillion miles? I am not concern with the feasibility of actually making the trip, I am interested in the math.

The formula is

distance / speed = time

Really…

Answer by Karle
120 trillion miles divided by 186,282 miles per second which is the speed of light u do the math since u are interested in it

Answer by kuiperbelt2003
time = dist/speed = 120×10^12 miles/1.86×10^5mi/s = 6.44×10^8 secs or approx 20.45yrs

Answer by steve c
ok take the speed of light 186,000 miles a second.
/ that into 120 trillion miles

Answer by RickB
I advise you to trust your 5th-grade teacher on this one. He or she undoubtedly taught you this formula:

time = distance / rate

“distance” is given as 120 trillion miles; “rate” is the speed of light, 186,282 miles per second.

Any scientific calculator will then give you the answer (which will of course be expressed in “seconds”). Or you can type this directly into the Google search box:

120,000,000,000,000 miles / c

When I do that, Google says:
“20.4133714 years”
