Question

Пешеход 1 км проходит за 2/9 часа за сколько часов он пройдет путь в 3/4 км

Answer 1

Найдем скорость пешехода. 1/(2/9)=4.5/км/ч./

3/4:4.5=0.75/4.5=75/450=1/6/часа/

1/6   часа это 10 минут.

Answer 2

Решение:

S=Vt

1=2/9×x

x=1÷2/9=4,5 км/ч - V

3/4=t×4,5

t=3/4÷4,5=1/1 ч

Ответ:1/6 ч или 10 мин

Answer 3

To find out how long it will take for the pedestrian to cover a distance of 3/4 km, we can use the concept of proportionality.

Let's set up a proportion:

Time taken to cover 1 km = 2/9 hours Time taken to cover 3/4 km = ?

The proportion can be written as:

(1 km) / (2/9 hours) = (3/4 km) / (x hours)

To solve for x (time taken to cover 3/4 km), we can cross-multiply:

1 km * x hours = (2/9 hours) * (3/4 km)

Now, let's perform the calculations:

x = (2/9) * (3/4) / 1 x = 6/36 x = 1/6

So, the pedestrian will cover a distance of 3/4 km in 1/6 hours, which is equivalent to 10 minutes (since 1 hour = 60 minutes).

Therefore, it will take the pedestrian 10 minutes to cover a distance of 3/4 km.
