Problem Description

You have provided a problem statement that involves a boat and a motorboat. The boat has a speed of 8 km/h, and the motorboat has an unknown speed. The distance traveled by the boat is 32 km, while the distance traveled by the motorboat is 80 km. The time taken for both the boat and the motorboat is the same. You want to find the speed of the motorboat.

Solution

To solve this problem, we can use the formula:

Speed = Distance / Time

Since the time taken by both the boat and the motorboat is the same, we can equate their speeds to find the speed of the motorboat.

Let's calculate the speed of the motorboat using the given information.

Calculation

The speed of the boat is given as 8 km/h, and the distance traveled by the boat is 32 km.

Using the formula, we can calculate the time taken by the boat:

Time taken by the boat = Distance / Speed = 32 km / 8 km/h = 4 hours

Now, let's calculate the speed of the motorboat using the distance traveled by the motorboat and the time taken by both the boat and the motorboat.

Speed of the motorboat = Distance / Time = 80 km / 4 hours = 20 km/h

Therefore, the speed of the motorboat is 20 km/h.

Answer

The speed of the motorboat is 20 km/h.
