Answer 2

Calculation of the Total Distance Traveled by Postman Pechkin

To calculate the total distance traveled by Postman Pechkin, we need to consider two parts of his journey: the first part where he traveled at a certain speed for 2 hours, and the second part where he reduced his speed by 2 km/h and traveled for an additional 3 hours.

Let's break down the calculation step by step:

1. In the first part of the journey, Postman Pechkin traveled 36 km in 2 hours. This means his speed during this part of the journey was 36 km / 2 hours = 18 km/h.

2. In the second part of the journey, Postman Pechkin reduced his speed by 2 km/h. Therefore, his speed during this part of the journey was (18 km/h - 2 km/h) = 16 km/h.

3. Postman Pechkin traveled at this reduced speed for 3 hours. Therefore, the distance he covered during this part of the journey was 16 km/h * 3 hours = 48 km.

4. To find the total distance traveled, we need to add the distances covered in both parts of the journey. The total distance is 36 km + 48 km = 84 km.

Therefore, Postman Pechkin traveled a total distance of 84 km on his bicycle.
