Problema Solution
The capacity of a ferry boat is either 48 children or 36 adults. If 20 children are on the ferry boat, how many adults can still get on?
Answer provided by our tutors
20 children are on the boat this means there is room for 48 - 20 = 28 children more
let x be the number of adults that can still get on the boat. we have the following proportion
48 children to 36 adults = 28 children to x adults
48 : 36 = 28 : x
x = (36*28)/48
x = 21 adults
21 adults can still get on.
