  1. 0.5 t < 0.75

  2. 0.75 t < 1.1

  3. 1.1 t < 1.25

  4. 1.25 t < 1.50

B Correct answer
AI explanation

Using the formula time equals distance divided by speed, the time to walk 2.4 miles is 2.4 divided by 3, which is 0.8 hours. The time to walk 3.2 miles is 3.2 divided by 3, which is approximately 1.066 hours. Therefore, the number of hours t satisfies the inequality 0.75 is less than or equal to t which is less than 1.1.
