Question

Расстояние между городами А и В равно 525 км. из города А в город В выехал автобус со скоростью 50 км в час. Из города В в город А выехал мотоциклист со скоростью 55 км в час.Через сколько часов они встретятся?

Answer 1

1)55+50=105(км/ч)-скорость сближения
2)525÷105=5(ч)-встретятся
Ответ: через 5 часов

Answer 2

1) 50+55=105 (км) едут вместе
2) 525:105=5(ч) они встретятся
Ответ 5 часов

Answer 3

Calculation of Meeting Time

To calculate the time it takes for the bus and the motorcycle to meet, we need to determine the relative speed at which they are approaching each other. Since they are traveling towards each other, their speeds will add up.

The bus is traveling at a speed of 50 km/h, while the motorcycle is traveling at a speed of 55 km/h. Therefore, the relative speed at which they are approaching each other is 50 km/h + 55 km/h = 105 km/h.

To find the meeting time, we can divide the distance between the two cities by the relative speed:

Meeting time = Distance / Relative speed

Given that the distance between the cities A and B is 525 km, we can substitute the values into the formula:

Meeting time = 525 km / 105 km/h = 5 hours

Therefore, the bus and the motorcycle will meet after 5 hours.
