Best Answer

You first need a conversion factor:

1 mile ~= 1.61 km


To do the conversion, use dimensional analysis to ensure that the units cancel properly.


( 260 mile / hour ) ( 1.61 km / 1 mile ) = 260 x 1.61 km/hour

260 x 1.61 km/hour = 418.6 KPH


Since 260 MPH has 2 significant figures in it, round and get 420 KPH.
