Question 851555
Think of the meeting happening in reverse.  What if they start at the meeting point but drive backward; one at 60 km/hr and the other at 90 km/hr.  What is the sum of their distances after 3 minutes?


{{{3*minutes(1*hour/(60*minutes))=(1/20)hours}}}


How far is {{{60*(1/20)+90(1/20)}}} ?
