Question

Пешеход затратил на путь 2,5 ч двигаясь со скоростью 3,6 км/ч сколько времени затратит пешеход на тот же путь если его скорость будет равна 4,5 км/ч

Answer 1

Ответ : Пешеход потратит  (2,5*3,6) /4,5 = 2 часа

Answer 2

Calculation of Time Taken

To calculate the time taken by a pedestrian to travel a certain distance at different speeds, we can use the formula:

Time = Distance / Speed

Given that the pedestrian initially traveled the distance in 2.5 hours at a speed of 3.6 km/h, we can calculate the distance using the formula:

Distance = Speed * Time

Let's calculate the distance first:

Distance = 3.6 km/h * 2.5 h = 9 km

Now, we can calculate the time taken to travel the same distance at a speed of 4.5 km/h:

Time = Distance / Speed = 9 km / 4.5 km/h = 2 hours

Therefore, the pedestrian will take 2 hours to travel the same distance at a speed of 4.5 km/h.

Conclusion

The pedestrian will take 2 hours to travel the same distance if their speed is 4.5 km/h.
