Question

Some people are seated in a bus. The number of

rows in the bus is equal to five times the seats in one
row. If the total number of seats in the bus is 180,
find the number of seats in one row.

Answer 1

6

Explanation:

Let the number of seats in one row be
`x`, then the number of rows will be
`5x`.

So the total number of seats will be
`x*5x=5x^2`, and that's equal to 180.

We have

`5x^2=180\\x^2=36`

And since
`x` has to be a positive number because it represents the number of seats, we know that
`x=6`.

So the number of seats in one row is 6.
