Question

Из двух городов отправились Одновременно навстречу друг другу два поезда со скоростями 48 км и 54 км ч найдите расстояние между городами если Поезда встретились через 4 часа после начала движения

Answer 1

1) 48*4=192(км) расстояние 1-ого поезда
2) 54*4=216(км) расстояние 2-ого поезда
3) 192+216=408(км)
Ответ: 408 км расстояние двух поездов.

Answer 2

1) 48+54=102(общая скорость)
2)102*4=408(км S)
S=T*V
V=S:T
T=S:V

Answer 3

Calculation of Distance between Two Cities

To find the distance between two cities, we can use the formula:

Distance = Speed x Time

Given that two trains are traveling towards each other with speeds of 48 km/h and 54 km/h, and they meet after 4 hours, we can calculate the distance between the two cities.

Let's calculate the distance step by step:

1. Calculate the total distance covered by both trains: - Train 1: Speed = 48 km/h, Time = 4 hours - Train 2: Speed = 54 km/h, Time = 4 hours

Using the formula Distance = Speed x Time, we can calculate the distance covered by each train: - Distance covered by Train 1 = 48 km/h x 4 hours = 192 km - Distance covered by Train 2 = 54 km/h x 4 hours = 216 km

2. Calculate the total distance between the two cities: - Total distance = Distance covered by Train 1 + Distance covered by Train 2 - Total distance = 192 km + 216 km = 408 km

Therefore, the distance between the two cities is 408 km.

Please note that the above calculation assumes that the trains are traveling towards each other on the same track and that their speeds remain constant throughout the journey.
