You can put this solution on YOUR website!
+t+=+d%2Fr+
( miles ) = ( km )x( mi/km )
( miles ) = +9.5%2A10%5E12%2A.62+
( miles ) = +5.89%2A10%5E12+
+t+=+%28+5.89%2A10%5E12+%29+%2F+17000+
+t+=+%28+5.89+%2F+1.7+%29%2A%28+10%5E12+%2F+10%5E4+%29+
+t+=+3.465%2A10%5E8+ hrs
This is the time to travel +1+ light year
For +3+ light years:
+t+=+3%2A3.465%2A10%5E8+
+t+=+10.395%2A10%5E8+
+t+=+1.0395%2A10%5E9+ ( scientific notation )
