Question

Помогите сделать задачу . задача такая . Скорость товарного поезда 76 км/ ч. Это в 3 раза меньше, чем скорость экспресса. На сколько километров больше проедет экспресс за 4 чса, чем товарный поезд за то же время?

Answer 1

Скорость экспресса 76*6=228км.ч
228*4=912 км проедет экспресс
76*4=304 км проедет товарный поезд
912-304=608 км проедет экспресс больше чем товарный поезд

Answer 2

1) 76*3=228 км/ч- скорость экспресса
2) 76*4=304 км - проедет товар п
3) 228*4=912км - проедет экспресс
4)912-304=608 км - на столько км больше проедет эксп
Ответ: На 608 км

Answer 3

Task Analysis

The task requires finding out how much farther an express train will travel in 4 hours compared to a freight train, given that the freight train's speed is three times slower than the express train's speed.

Given Information

- Speed of the freight train: 76 km/h - The speed of the express train is three times faster than the freight train.

Solution

To solve this problem, we can calculate the distance traveled by each train in 4 hours and then find the difference.

Calculations

1. Distance traveled by the freight train in 4 hours: - Speed of the freight train = 76 km/h - Time = 4 hours - Distance = Speed × Time - Distance = 76 km/h × 4 h = 304 km

2. Speed of the express train: - Given that the speed of the freight train is three times slower than the express train, we can calculate the speed of the express train. - Speed of the express train = 3 × 76 km/h = 228 km/h

3. Distance traveled by the express train in 4 hours: - Speed of the express train = 228 km/h - Time = 4 hours - Distance = Speed × Time - Distance = 228 km/h × 4 h = 912 km

Answer

The express train will travel 608 kilometers farther than the freight train in 4 hours.
