Question

At every company meeting, the president speaks for 20 minutes and then takes questions from her employees.
Let q represent the number of minutes she spends answering questions and t represent the total number of minutes the meeting lasts.
Find the value of t when q=10.
t=

Answer 1

The total duration of the meeting \( t \) consists of the time the president speaks and the time she spends answering questions.

According to the description:

• The president speaks for 20 minutes.
• The time spent answering questions is represented by \( q \).

Therefore, we can express the total time \( t \) as: \[ t = 20 + q \]

If we are given that \( q = 10 \) minutes, we can substitute this value into the equation:

\[ t = 20 + 10 = 30 \]

Thus, the value of \( t \) when \( q = 10 \) is: \[ \boxed{30} \]
