You can put this solution on YOUR website! Use the conversion: m = in mile = ft
--------------------------
In terms of just units:
[ m/sec ] x [ inches/m ] x [ ft/inches ] x [ miles/ft ] x [ sec/min ] x [ min/hr ] = [ miles/hr ]
Can you follow all the cancellations? Suppose I just rewrite it this way:
[ m/m ] x [ inches/inches ] x [ ft/ft ] x [ sec/sec ] x [ min/min ] x [ miles/hr ] = [ miles/hr ]
( As long as I didn't mess it up ! )
---------------------------------
Now just plug in numbers to solve.
About 3,252.5 miles/hr
-----------------------
Check carefully -I could have got my eyes crossed!
