**Motion and Time:**

Motion is defined as the change in position of an object with respect to its surroundings. Time is a measure of the duration of an event. The relationship between motion and time is important in understanding the speed and velocity of an object.

**Speed and Velocity:**

Speed is the rate at which an object covers a certain distance in a given amount of time. It is calculated by dividing the distance covered by the time taken. Velocity, on the other hand, is the speed of an object in a given direction. It is a vector quantity, meaning it has both magnitude and direction.

**Given Information:**

According to the given information, a body covers 26 meters in the 10th second, 28 meters in the 11th second, 30 meters in the 12th second, and 32 meters in the 13th second. We need to determine the starting point of the body.

**Analysis:**

To solve this problem, we can use the concept of average speed. Average speed is calculated by dividing the total distance traveled by the total time taken. In this case, we can calculate the average speed for each second and then find the starting point of the body.

Let's break down the given information:

- Distance covered in the 10th second = 26 meters
- Distance covered in the 11th second = 28 meters
- Distance covered in the 12th second = 30 meters
- Distance covered in the 13th second = 32 meters

**Calculations:**

To find the average speed for each second, we divide the distance covered by the time taken:

- Average speed in the 10th second = 26 meters / 1 second = 26 m/s
- Average speed in the 11th second = 28 meters / 1 second = 28 m/s
- Average speed in the 12th second = 30 meters / 1 second = 30 m/s
- Average speed in the 13th second = 32 meters / 1 second = 32 m/s

**Determining the Starting Point:**

To determine the starting point of the body, we need to find the distance covered in the first 9 seconds. We can do this by subtracting the distances covered in the 10th, 11th, 12th, and 13th seconds from the total distance covered in those seconds:

- Total distance covered in the 10th to 13th seconds = 26 + 28 + 30 + 32 = 116 meters

Now, let's calculate the distance covered in the first 9 seconds:

- Distance covered in the first 9 seconds = Total distance covered - Distance covered in the 10th to 13th seconds
- Distance covered in the first 9 seconds = 116 meters - (26 + 28 + 30 + 32) meters
- Distance covered in the first 9 seconds = 116 meters - 116 meters
- Distance covered in the first 9 seconds = 0 meters

Therefore, the starting point of the body is at 0 meters.
