Solution:

Duration of time for which a contestant have to speak = 5 minutes (300 Seconds)

Point lost by a contestant for over-speaking that is for more than 5 minutes for each second = 3 points

Point lost by a contestant for speaking less than 5 minutes on each second = 3 points

So, the expression which can determine ,the number of points a contestant loses if she speaks for x seconds.

⇒Number of points a contestant loses if she speaks for x seconds=3 \times\left |x-300 \right |

For, example if a contestant speaks for 290 seconds,Points lost by contestant = 3 \times\left |290-300 \right |=3 × 10= 30 Points

If a contestant speaks for 305 seconds,Points lost by contestant = 3 \times\left |305-300 \right |=3 × 5= 15 Points

Option (A)= 3 \times\left |x-300 \right | is right choice describing above situation.

First, let's make an expression!

If you meant a different equation..sorry
