Conversion question?

// Well, you didn't supply the distance. Google Maps has the distance

// between Seville and Madrid as 534km by car. Obviously, trains will

// have a somewhat shorter, more direct distance, but we'll use 534km for now.

// Use the distance formula: distance = rate x time

// So,

.....534km = r x 2.5 hours

.....r = 534km / 2.5 hours

.....r = 213.6 km/hr....................ANS

// To find the rate in miles/hour, we need to convert km to miles

// using the conversion 1 km = 0.6213712 mile

1 km...................534 km

---------------------- = -----------

0.6213712 mile..........r

......(0.6213712 mile) (534 km)

r = --------------------------------------

.................1 km

r = 331.8122208 mph........................ANS

missing the distance. I can look it up, but the rail distance is not that easy to find.
