Calculation of Time Taken by Tourists

To calculate the time taken by the tourists, we need to determine the time taken for each segment of the journey and then add them together.

Given information: - Distance covered by the tourists in a day: 22 km - Speed of the tourists: 4 km/h for a certain distance and 5 km/h for the remaining distance

Let's break down the journey into two segments:

1. Segment 1: The tourists traveled at a speed of 4 km/h for a certain distance. 2. Segment 2: The tourists traveled at a speed of 5 km/h for the remaining distance.

To calculate the time taken for each segment, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken for each segment:

1. Segment 1: - Distance: Let's assume the distance covered in this segment is 'x' km. - Speed: 4 km/h - Time taken for Segment 1: x / 4 hours

2. Segment 2: - Distance: The remaining distance is 22 km - x km. - Speed: 5 km/h - Time taken for Segment 2: (22 - x) / 5 hours

To find the total time taken by the tourists, we need to add the time taken for both segments:

Total Time = Time taken for Segment 1 + Time taken for Segment 2

Now, let's solve for 'x' and calculate the total time taken by the tourists.

Calculation Steps:

1. Let's assume the distance covered in Segment 1 is 'x' km. 2. The distance covered in Segment 2 is 22 km - x km. 3. Time taken for Segment 1: x / 4 hours 4. Time taken for Segment 2: (22 - x) / 5 hours 5. Total Time = Time taken for Segment 1 + Time taken for Segment 2

Solution:

To calculate the total time taken by the tourists, we need to solve the equation:

x / 4 + (22 - x) / 5 = 3

Simplifying the equation:

5x + 4(22 - x) = 60

Solving for 'x':

5x + 88 - 4x = 60

x + 88 = 60

x = 60 - 88

x = -28

Since the value of 'x' is negative, it means that the distance covered in Segment 1 is negative, which is not possible. Therefore, there seems to be an error in the given information or calculation.
