Allen is running a marathon. He would like to finish the race in under 5.5 hours. He has already run 3 hours. The inequality represents the situation. Which number line shows how much longer Allen can run and still meet his goal?

20 pts

x < 2.5

Step-by-step explanation:

Allen has already run 3 hours and will run x amount more to finish. This is 3+x. He must finish under or less than 5.5 hours. So 3 + x < 5.5. You solve and find x < 2.5.

The inequality that represents the situation is:

x<2.5

Step-by-step explanation:

Allen is running a marathon.

He has already run 3 hours.

Let he runs for x hours more.

He would like to finish the race in under 5.5 hours.

i. e. 3+x must be less than 5.5

i. e. 3+x<5.5

i. e. x<2.5
