Three friends take a long trip using a tandem bicycle for 2 persons. Because the
bike riders travel at 30 km/hr, independent of number of riders, and all three persons walk at a speed of 5 km/hr, they proceed as follows: to start the journey, friend ''A ,B" ride the bicycle and friend "C" walks; after a while, friend ''A'' drops off friend ''B'' who starts walking, and ''A'' rides the bicycle alone in the reverse direction. when ''A'' and ''C'' meet, they turn the bicycle around and ride forward until they catch up with ''B'' .At that time the three friends have completed a basic cycle of their strategy, which they repeat a number of times until they reach their destination What is their average speed? you might solve it either graphically or algebraically
