Question

Пешеход двигаясь со скоростью 3,6 км/ч потратил на весь путь 2,5 ч. Сколько времени уйдёт у него на тот же путь если его скорость будет равна 5 км/ч помогите пожалуйста

Answer 1

3,6*2,5=9 км - длина пути
9/5=1,8 ч 
Ответ: 1,8 ч уйдет на тот же путь при скорости 5 км/ч

Answer 2

Calculation of Time Taken at Different Speeds

To calculate the time taken for the pedestrian to cover the same distance at a different speed, we can use the formula:

Time = Distance / Speed

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

Distance = Speed * Time

Substituting the given values, we have:

Distance = 3.6 km/h * 2.5 hours

Calculating the distance, we find that the pedestrian covered a distance of 9 kilometers.

Now, to find the time taken at a speed of 5 km/h, we can use the formula:

Time = Distance / Speed

Substituting the distance and speed values, we have:

Time = 9 kilometers / 5 km/h

Calculating the time, we find that it will take the pedestrian 1.8 hours to cover the same distance at a speed of 5 km/h.

Therefore, if the pedestrian's speed is increased to 5 km/h, it will take them approximately 1.8 hours to cover the same distance.

Please note that the calculations provided are based on the given information and assumptions.
