Question

Теплоход от пристани г. Вязьма да г. Николаевска шёл 9 часов со скоростью 30 км/ч . А поезд ехал от г . Вязьма до г. Николаевска 4 часов со скоростью 80км/ч. Какой путь длинее железно дорожный или речной . Записать по действиям

Answer 1

1) 30 * 9 = 270 км - по воде
2) 80 * 4 = 320 км - на поезде
 270 < 320
3) 320 - 270 = 50 км - разница

Ответ : железнодорожный путь длиннее (на 50 км).

Answer 2

9*30=270 км от г.Вязьма до г.Николаевска  речной путь
4*80=320 км от г.Вязьма до г.Николаевска железнодорожный путь
320-270=50 км на столько длиннее железнодорожный путь

Answer 3

Calculating the Distances Traveled

To determine which distance is longer, let's calculate the distances traveled by the ship and the train.

Distance traveled by the ship: The ship traveled for 9 hours at a speed of 30 km/h.

Using the formula: distance = speed × time, we can calculate the distance traveled by the ship: distance_ship = 30 km/h × 9 h = 270 km

Distance traveled by the train: The train traveled for 4 hours at a speed of 80 km/h.

Using the same formula: distance = speed × time, we can calculate the distance traveled by the train: distance_train = 80 km/h × 4 h = 320 km

Comparing the Distances

Comparing the distances: The distance traveled by the ship is 270 km, while the distance traveled by the train is 320 km.

Therefore, the distance traveled by the train (320 km) is longer than the distance traveled by the ship (270 km).

So, the railway distance is longer than the river distance.

This calculation is based on the given speeds and times for both the ship and the train
