Question

Yu Jie can complete a 4 foot by 6 foot quilt in

16 days, while Mufeed can complete the same
task in 12 days. If they solicit Mya's help, who
can complete the task in 14 days by herself,
how long will it take the three of them to
complete a 4 foot by 6 foot quilt?

Answer 1

4 44/73 days to complete a 4 foot by 6 foot quilt.

Explanation:

x/16 +x/12+ x/14=1

336(x/16 +x/12+ x/14)=336(1)

21x+28x+24x=336

73x=336

x= 4.60273972603 and that would reduce to 4 44/73

I think this is right
