Time spent bicycling: , although 42 mph is EXTREMELY HIGH speed for a bicycle.
Then again, it appears that currently, people are making up all types of RIDICULOUS and NONSENSICAL math problems without even ensuring that 
they make sense. I feel sorry for these kids who're expecting to learn and apply common sense. How can they learn from these people?


Another RIDICULOUS one is the one below who claims that Jim walks at a rate of 42 mph. He needs to be BANNED!

Act as though you don't see his ATTEMPT, or just simply do THIS to it!!

              SPEEDS         TIMES     DISTANCES

Bicycling        4             x         4x

Walking          42           7-x       42(7-x)

Total                         7          237
