mathmale · Answer

For a quick first estimate, assume that 1 mile = 1.6 Km.  What conversion factor does this give us?

Can you now apply this conversion factor to change from 140 Km/hr to miles/minute?  Note that you'll also have to convert hours to minutes (ending up with a conversion factor).

mathmale · Answer

1.6 Km is equal to approx. 1 mile.

1 mile is 5,280 feet.

How many minutes in 1 hour?
