Question

Из города А и В навстречу друг другу выехали одновременно два автомобиля скорость одного автомобиля 60 км / ч а другого на 15км / ч больше Какое расстояние будет через 2 часа между автомобилями если расстояние между городами 7 км?

Answer 1

1)60+15=75(км/ч)-скорость второго автомобиля
2)60+75=135(км/ч)-скорость сближения
3)135*2=270(км)-проехали два автомобиля
4)270-7=263(км)
Ответ:263км

Answer 2

Calculating the Distance Between Two Cars

Two cars, A and B, are traveling towards each other from cities A and B, respectively. Car A is traveling at a speed of 60 km/h, while car B is traveling at a speed 15 km/h faster than car A. The distance between the cities is 7 km. We need to calculate the distance between the two cars after 2 hours.

Solution

To find the distance between the two cars after 2 hours, we can use the formula: distance = (speed of car A + speed of car B) * time

Given: - Speed of car A = 60 km/h - Speed of car B = 60 km/h + 15 km/h = 75 km/h - Time = 2 hours

Using the formula: distance = (60 km/h + 75 km/h) * 2 hours

Calculation

distance = (60 km/h + 75 km/h) * 2 hours distance = (135 km/h) * 2 hours distance = 270 km

So, the distance between the two cars after 2 hours will be 270 km.
