Question

Из пункта А в пункт В выехала грузовая машина. Одновременно с ней их пункта В в пункт А выехала легковая машина. Грузовая машина через 2 часа после начала движения встретила легковую и еще через 3 ч прибыла в пункт В. Сколько времени потратила легковая машина на путь из В в А?

Answer 1

грузовая ехала 3+2 = 5 часов

легковая проехала путь до встречи 2 часа, а грузовая за 3,

значит скорость легковой  3/2 = 1,5 раза больше скорости грузовой

2+ 2: 1,5 = 2+ 4/3 = 3 1/3 часа = 3 час 20 минут

Answer 2

Problem Analysis

We have a situation where a truck and a car start their journey simultaneously from point A to point B and vice versa. The truck meets the car after 2 hours of travel and arrives at point B 3 hours after that. We need to determine how much time the car spent traveling from point B to point A.

Solution

Let's break down the problem step by step:

1. The truck meets the car after 2 hours of travel. This means that the car has been traveling for 2 hours when they meet. 2. After the meeting, the truck continues to travel for another 3 hours and arrives at point B. This means that the total travel time for the truck is 2 + 3 = 5 hours. 3. Since the car and the truck started their journey simultaneously, the car also spent 5 hours traveling from point A to point B. 4. Therefore, the car spent 5 hours traveling from point B to point A.

Answer: The car spent 5 hours traveling from point B to point A.

Explanation

The truck and the car started their journey simultaneously. After 2 hours of travel, they met. The truck continued to travel for another 3 hours and arrived at point B. Since the car and the truck started at the same time, the car also spent 5 hours traveling from point A to point B. Therefore, the car spent 5 hours traveling from point B to point A.
