Question

A team of 4 students participating in a math competition can solve nine problems correctly in 30 minutes. How many problems should a team of 5 students be able to solve?

Answer 1

A team of `5` equally qualified students should be able to solve `11` problems.

Explanation:

`4` students can solve `9` problems in `30m`.
`5` students can solve `x` problems in `30m`.

Then in the same `30m`: `4/9=5/x to and4x = 45`

So: `x=45/4=11 1/4`

But we know that `1/4` of a math question would be outrageous.

So the answer to this math question is `11`.
