## anonymous one year ago directly proportional question

1. anonymous

at a science conference, the length of the question period is directly proportional to the length of the session . if there is a 15-minute question period in a 50-m. session ,how many minutes long is the question period in an 30 -minute session at this conference?

Let x be the length of the question period after a 30-minute session. Then we can write: $\large \frac{15}{50}=\frac{x}{30}$ Now you need to solve the equation to find the value of x.
