Question

Две машины выехали одновременно из двух городов навстречу друг другу.Через 3ч после начала движения машины встретились.Какое расстояние проехала каждая до места встречи,если скорость одной машины 85км/ч,а скорость другой - 70км/ч?

Answer 1

85х3=255(км)-первая 70х3=210(км)-вторая

Answer 2

85*3+70*3=255+210=465

Answer 3

Problem Analysis

We are given that two cars start simultaneously from two different cities and meet after 3 hours of travel. The speed of one car is 85 km/h, and the speed of the other car is 70 km/h. We need to find the distance traveled by each car before they meet.

Solution

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each car.

1. Car 1: - Speed of Car 1 = 85 km/h - Time = 3 hours - Distance traveled by Car 1 = Speed × Time = 85 km/h × 3 hours = 255 km

2. Car 2: - Speed of Car 2 = 70 km/h - Time = 3 hours - Distance traveled by Car 2 = Speed × Time = 70 km/h × 3 hours = 210 km

Therefore, Car 1 traveled 255 km and Car 2 traveled 210 km before they met.

Answer

The distance traveled by each car before they met is as follows: - Car 1 traveled 255 km - Car 2 traveled 210 km
