Explanation:

Let’s break it down:

- The speed of the fast boat downstream = $26\text{km/hr}+2\text{km/hr}=28\text{km/hr}$.

- The speed of the other boat upstream = $28\text{km/hr}-2\text{km/hr}=26\text{km/hr}$.

- Combined effective speed = $28\text{km/hr}+26\text{km/hr}=54\text{km/hr}$.

- They need to cover the distance of 80 km together.

- Time taken to meet = $\frac{80\text{km}}{54\text{km/hr}}˜1.48\text{hours}$.

The correct answer is:

Option: 1, 1.48 hours
