    Answer:

    1.27 hours

    Step-by-step explanation:

    The first step in this process would be adding both rates of Leila and Han together. We know Leila walks at 2.5 miles per hour and Han at 3 miles per hour.

    2.5 + 3 = 5.5

    We got our sum as 5.5, so now we must complete Step 2, which is the final step. We must divide 7 by 5.5.

    7 / 5.5 = 1.2727...

    1.2727 ≈ 1.27

    the answer to the Question is 1.27 hours.
