Question

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 3 t less-than 5. 5 represents the situation. Which number line shows how much longer Allen can run and still meet his goal? A number line going from 0 to 3. An open circle is at 2. 5. Everything to the left of the circle is shaded. A number line going from 0 to 3. A closed circle is at 2. 5. Everything to the left of the circle is shaded. A number line going from 0 to 3. An open circle is at 2. 5. Everything to the right of the circle is shaded. A number line going from 0 to 3. A closed circle is at 2. 5. Everything to the right of the circle is shaded.

Answer 1

Explanation:

Question : 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 3 + t less-than 5. 5 represents the situation. Which number line shows how much longer Allen can run and still meet his goal?

Total time it would take allen to complete the race is less than 5.5 hours.

Time = 3 hours

inequality : 3 + t < 5.5

t = time left

solve for t

t < 2.5

time left is < 2.5 hours.

An open circle is at 2. 5. Everything to the left of the circle is shaded.
