In 14 hours, the jet will have traveled 2540 miles.
1) first, make a equation to be able to solve; 420/2 = x/14
2) next, you have to figure out what times 2 equals 14. here, it is 7. after that, you multiply 7 by 2 (which is 14) and do the same to the top of the fraction (240 times 7)
3) after you multiply it you get 240/2 = 2540/14
hope this helps !!
