How many hours would it take fran to swim 0.8 miles upstream

Fran's upstream speed (against the current):

       2.7 km/hr - 0.8 km/hr = 1.9 km/hr

Now we can answer each question by manipulating the distance formula to come up with our expression for calculating time:

   rate x time = distance

            time = distance / rate      

   Fran's upstream time = 9 / 1.9 = 4.7 hrs

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

understand that i don't know the answers

will someone answer his question
