Answer:
1.27 hours
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](https://img.qammunity.org/2022/formulas/mathematics/high-school/p62i10zyeifcb06brcj1wrjpotx2xxl6e9.png)
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...](https://img.qammunity.org/2022/formulas/mathematics/high-school/hmzcni7td7eug8x0xh8g13y4ttnsgft27o.png)
1.2727 ≈ 1.27
the answer to the Question is 1.27 hours.
