Problem Analysis

We have two boats that are moving towards each other. The distance between them is initially 96 km. One boat is moving at a speed of 35 km/h, and the other boat is moving at a speed of 40 km/h. We need to find the time it takes for the boats to meet.

Solution

To find the time it takes for the boats to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two boats since they are moving towards each other.

Let's calculate the relative speed first:

Relative Speed = Speed of Boat A + Speed of Boat B

Now, let's substitute the values into the formula and calculate the time it takes for the boats to meet.

Calculation

Speed of Boat A = 35 km/h Speed of Boat B = 40 km/h

Relative Speed = 35 km/h + 40 km/h = 75 km/h

Distance = 96 km

Time = Distance / Relative Speed = 96 km / 75 km/h

Answer

The time it takes for the boats to meet is approximately 1.28 hours.
