4-2=2 (км/ч) скорость пешехода на обратном пути 
16:2=8 (км/ч ) время на обратный путь 

Answer 2

Ответ 8ч он потратил на обратный путь

Answer 3

Calculation of Time Spent on the Return Journey

To calculate the time spent on the return journey, we need to consider the distance covered and the speed at which the pedestrian traveled.

Given: - Distance covered on the forward journey: 16 km - Time taken on the forward journey: 4 hours - Speed reduction on the return journey: 2 km/h

To find the time spent on the return journey, we can use the formula:

Time = Distance / Speed

Let's calculate the time spent on the return journey step by step:

1. Calculate the speed on the forward journey: - Speed = Distance / Time = 16 km / 4 hours = 4 km/h

2. Calculate the speed on the return journey: - Speed = Speed on the forward journey - Speed reduction = 4 km/h - 2 km/h = 2 km/h

3. Calculate the time spent on the return journey: - Time = Distance / Speed = 16 km / 2 km/h = 8 hours

Therefore, the pedestrian spent 8 hours on the return journey.
