Question

Автобус и автомашина движутся по шоссе навстречу друг другу.Сейчас расстояние между ними равно 250 км. Через сколько часов они встретятся , если автомашина едет со скоростью 80 км, ч, а автобус 45 км ч

Answer 1

S:(v1+v2)
250÷(80+45)=2(ч)
Они встретятся через 2 ч

Answer 2

250-(80+45)=120 мин - 2 часа

Answer 3

Calculation of Meeting Time

To calculate the time it takes for the bus and the car to meet, we need to consider their speeds and the initial distance between them.

Given: - Speed of the car = 80 km/h - Speed of the bus = 45 km/h - Initial distance between them = 250 km

To find the meeting time, we can use the formula:

Meeting Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the car and the bus.

Let's calculate the meeting time:

Relative Speed = Speed of Car + Speed of Bus = 80 km/h + 45 km/h = 125 km/h

Meeting Time = 250 km / 125 km/h = 2 hours

Therefore, the car and the bus will meet after 2 hours.
