Question 169591
diameter of a quarter is 24.26 mm
diameter of a dime is 17.91 mm

1 km equals 1000000 milimeters

so for quarters divide 1000000/24.26=41220
.......dimes    divide 1000000/17.91=55834

41220 multiplied by .25=$10305
55834 multiplied by .10=$5583

almost twice as money in quarters....I think I would choose quarters..lol

interestingly enough if you stacked both 1 kilometer high you would still end up with almost twice the value in quarters.
