Question

Расстояние между двумя посёлка мм равно 39км. из одного посёлка вышел первый пешеход со скоростью 4км/ч, а из другого посёлка через часа навстречу ему - второй пешеход со скоростью 5км/ ч. сколько времени будет идти второй пешеход до встречи с первым?

Answer 1

Через сколько часов пойдет навстречу другой пешеход?

Answer 2

Calculating the Time for the Second Pedestrian to Meet the First One

The distance between the two villages is 39 km. The first pedestrian walks at a speed of 4 km/h, and the second pedestrian walks at a speed of 5 km/h.

To calculate the time it takes for the second pedestrian to meet the first one, we can use the formula:

Time = Distance / Relative Speed

Where: - Time is the time taken for the second pedestrian to meet the first one. - Distance is the total distance between the two pedestrians. - Relative Speed is the combined speed of both pedestrians.

Using this formula, we can calculate the time it takes for the second pedestrian to meet the first one.

The relative speed of the two pedestrians is the sum of their individual speeds, which is 4 km/h + 5 km/h = 9 km/h.

Now, we can calculate the time it takes for the second pedestrian to meet the first one:

Time = 39 km / 9 km/h

Time = 4.33 hours

So, the second pedestrian will take approximately 4.33 hours to meet the first pedestrian.
