Q. Romi   and   Sony are  two  brothers. They wanted to go to the library. Just as they were leaving, father   stopped   Sony.   So,   Romi   started   alone.   A  little  while   later,   Sony   ran   and   caught   up with   Romi.   Then   after   going  together for some time they reached the library, where they sat

down   and read   some   books.   All   this is  shown  in  the   form   of  a   graph.  In   the   graph,   their
journeys   are   depicted   by   separate   lines   marked   with   different   symbols.   Look   at  the   graph
and   answer the  following questions:

        1.   What   was   Romi’s   speed   per   minute while   he was moving?
        2.   For   how   long did father   keep   Sony waiting?
        3.  How   far   from   home   did  Sony   finally  meet Romi?
        4.  What   distance   did the   two  of  them  cover   together?
        5.  For   how  much   time   did they   walk   together?
        6.  How   far   is  the   library from home?
