Question

Из двух городов одновременно навстречу друг другу выехали два автомобиля.Один двигался со скоростью 70 км/ч и он проехал до встречи 210 км.Какое расстояние до встречи проехал второй автомобиль,если он двигался со скоростью 55км/ч?

Answer 1

Формулы:
1) Время = расстояние деленное на скорость.
2) Расстояние = время умноженное на скорость.
-------------------
1) 210/70 = 3ч - затратил первый автомобиль на дорогу.
2) 55*3 = 165 км/ч - проехал второй.

Ответ: 165км

Answer 2

Problem Analysis

Two cars are traveling towards each other from different cities. The first car is traveling at a speed of 70 km/h and has traveled 210 km before meeting the second car. The second car is traveling at a speed of 55 km/h. We need to find out how far the second car has traveled before meeting the first car.

Solution

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

Let's calculate the time it took for the first car to meet the second car using the given distance and speed. Then, we can use this time to calculate the distance traveled by the second car.

Calculation

The time taken by the first car to meet the second car can be calculated using the formula: time = distance / speed

For the first car: - Speed = 70 km/h - Distance = 210 km

Using the formula, we can calculate the time taken by the first car to meet the second car: time = 210 km / 70 km/h = 3 hours

Now, we can calculate the distance traveled by the second car using the time and speed of the second car: distance = speed × time distance = 55 km/h × 3 hours = 165 km

Answer

The second car traveled 165 km before meeting the first car.
