Question

От двух авто вокзала одновременно отправились навстречу один в другом в автобус со скоростью 50 км/с и 40 километров в час расстояние между вокзал = 180 км через сколько автобус и встретиться

Answer 1

50+40=90(км/ч)
180/90=2 часа
Ответ: 2

Answer 2

50+40=90 км/час суммарная скорость
180/90=2 час через 2 часа они встретятся 

Answer 3

Problem Analysis

We are given that two vehicles start from opposite ends of a train station and travel towards each other. The first vehicle is a bus traveling at a speed of 50 km/h, and the second vehicle is traveling at a speed of 40 km/h. The distance between the two ends of the train station is 180 km. We need to determine how long it will take for the two vehicles to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it will take for the two vehicles to meet.

Calculation

The distance between the two vehicles is 180 km. The speed of the first vehicle (bus) is 50 km/h. The speed of the second vehicle is 40 km/h.

Using the formula time = distance / speed, we can calculate the time it will take for the two vehicles to meet.

For the first vehicle (bus): time1 = distance / speed1 = 180 km / 50 km/h

For the second vehicle: time2 = distance / speed2 = 180 km / 40 km/h

Answer

The first vehicle (bus) will take 3.6 hours to reach the meeting point, and the second vehicle will take 4.5 hours to reach the meeting point.

Therefore, the two vehicles will meet after approximately 3.6 hours.

Note: The exact meeting point can be calculated by multiplying the time it takes for the first vehicle to reach the meeting point by its speed or by multiplying the time it takes for the second vehicle to reach the meeting point by its speed.
