Many American cars feature speedometers that show kilometers per hour. If you are required to drive 500 miles, and you know that one kilometer is approximately 5/8 of a mile, how many kilometers would you cover in that journey?

Answer 1

Another proportional situation
miles/km = miles/km
(5/8) over 1km = 500miles/x km
solve for x

Answer 2

I still dont get it what would x be

Answer 3

distance = 500/(5/8) = 500 * 8/5 = 800 km.
