<PRE><B>Question 335298</B>
you want to go from 98 minutes at 5.9 miles/hour to kilometers
--
identity 1:  5.9 miles in one hour
identity 2:  1 hour equals 60 minutes
identity 3:  1 mile equals 1.61 kilometer
--
multiply identities such that units cancel out leaving you with kilometers
--

(98 minutes) *(5.9 miles/hour)*(1hour/60 minutes)*(1.61 km/1mile)
={{{((98)*(5.9)*(1.61)/60)*green(cross(minutes))*(red(cross(miles))/cross(hour))*(cross(hour)/green(cross(minutes)))*(km/red(cross(mile)))=15.52km}}}</PRE>
