OpenStudy (mathmale):
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).
OpenStudy (mathmale):
1.6 Km is equal to approx. 1 mile. 1 mile is 5,280 feet. How many minutes in 1 hour?
