Problema Solution
Every year on Earth Day, a group of volunteers pick up garbage at Hidden Falls Park. The time it takes to clean the beach varies inversely with the number of people picking up garbage. Last year,33 volunteers took 4 hours to clean the park. If 66 volunteers come to pick up garbage this year, how long will it take to clean the park?
Answer provided by our tutors
Let 'x' represent the number of hours that 66 volunteers need to pick up the garbage.
66x = 33*4 divide both sides by 66
x = 33*4/66
x = 2 hr
66 volunteers will need 2 hours to pick up the garbage this year.
