Question

Расстояние между сёлами 48 км .через сколько часов встретятся два пешехода ,которые вышли одновременно на встречу друг другу , если скорость одного 3 км / ч , а другого 5 км / ч?

Answer 1

48:(3+5)=48:8=6 часов

Answer 2

1) 3+5=8км/ч 2)48:8=6ч ответ:Через 6 часов

Answer 3

Calculating the Meeting Time of Two Pedestrians

To calculate the time it takes for two pedestrians to meet, we can use the formula:

Time = Distance / Relative Speed

Where: - Distance = 48 km - Speed of the first pedestrian = 3 km/h - Speed of the second pedestrian = 5 km/h

Using the given values, we can calculate the time it takes for the two pedestrians to meet.

Calculations

1. The relative speed of the two pedestrians is the sum of their individual speeds: - Relative Speed = 3 km/h + 5 km/h = 8 km/h.

2. Now, we can calculate the time it takes for the pedestrians to meet using the formula: - Time = Distance / Relative Speed - Time = 48 km / 8 km/h - Time = 6 hours.

Therefore, the two pedestrians will meet after 6 hours.

This calculation assumes that the pedestrians maintain a constant speed throughout their journey and that there are no other factors affecting their travel time.
