Question

Из двух посёлков навстречу друг другу одновременно вышли два пешехода. Скорость одного- 4км/ч, другого - 5км/ч. Найди расстояние между посёлками, если пешеходы встретились через 2 часа.

Answer 1

Чтобы найти расстояние, нужно скорость умножить на время.

1) 4*2=8(км)- расстояние, которое прошел первый пешеход за 2 часа.

2) 5*2=10(км)- расстояние, которое прошел второй пешеход за 2 часа.

3) 10+8=18(км)-расстояние между посёлками.

Answer 2

Calculating the Distance Between Two Villages

To find the distance between the two villages, we can use the formula: distance = speed * time. Given that two pedestrians, each walking at different speeds, met after 2 hours, we can calculate the distance between the villages using the following steps:

1. Calculate the Total Distance Covered by Both Pedestrians: - The first pedestrian's speed is 4 km/h, and the second pedestrian's speed is 5 km/h. - The total distance covered by both pedestrians can be calculated by adding the distances covered by each pedestrian.

2. Use the Formula to Calculate the Distance: - Using the formula distance = speed * time, we can calculate the total distance covered by both pedestrians.

Calculation Steps

1. Calculate the Distance Covered by the First Pedestrian: - Distance covered by the first pedestrian = speed * time = 4 km/h * 2 h.

2. Calculate the Distance Covered by the Second Pedestrian: - Distance covered by the second pedestrian = speed * time = 5 km/h * 2 h.

3. Calculate the Total Distance: - Total distance = Distance covered by the first pedestrian + Distance covered by the second pedestrian.

Calculation Results

1. Distance Covered by the First Pedestrian: - Distance = 4 km/h * 2 h = 8 km.

2. Distance Covered by the Second Pedestrian: - Distance = 5 km/h * 2 h = 10 km.

3. Total Distance: - Total distance = 8 km + 10 km = 18 km.

Therefore, the distance between the two villages is 18 kilometers.
