I'm terrible at math, so I'm sorry if I'm totally wrong, but I'm assuming you just take the average:
20+28=48m
48/2=24m
On average, it may take them 24m if they work together.
you can easily solve it by equating the fractions 4/13 and x/91
here, we suppose x as the number of people who can bowl.
4/13=x/91
or, 4/13×91=x (divide 91 by 13)
or, x=4×7
therefore, x=28
easy peesy lemon squeezy ;-)
