Answer 1

Ответ:

Пошаговое объяснение:

сложить скорости и умножить на

время (60+55)×3=115×3=345км

Answer 2

Problem Analysis

Two trains, 1 and 2, are traveling towards each other. Train 1 is traveling at a speed of 60 kilometers per hour, and train 2 is traveling at a speed of 55 kilometers per hour. They meet after 3 hours. We need to find the distance between points A and B.

Solution

Let's denote the distance between points A and B as D.

The total distance traveled by both trains when they meet is equal to the sum of the distances they have traveled.

For train 1, the distance traveled is given by the formula: distance = speed × time. For train 2, the distance traveled is also given by the formula: distance = speed × time.

Calculations

- The distance traveled by train 1 is 60 km/h × 3 h = 180 km. - The distance traveled by train 2 is 55 km/h × 3 h = 165 km.

When they meet, the total distance traveled by both trains is 180 km + 165 km = 345 km.

Therefore, the distance between points A and B is 345 kilometers.

Note: The above solution is based on the given information and calculations.
