Question

Теплоход за три дня прошёл 900км, причём во второй и третий день в два раза больше, чем в первый. Сколько километров проходил теплоход в каждый из этих дней?

Answer 1

Всего 900 км
1 день - ?
2 день - в 2 р > чем в 1 -?
3 день - в 2 р > чем в 1 -?

1) 1+2+2=5 частей всего
2) 900:5 = 180 км в 1 части (в первый день)
3) 180*2 = 360 км в 2-х частях (во  второй и  в третий день)

Answer 2

В первый день х  во второй и третий по 2х   х+2х+2х=900   х=180км  во 2-ой 180*2=360км и в 3-й  360км

Answer 3

Calculation of Distance Traveled by the Ship Each Day

To determine the distance traveled by the ship each day, we can use the information provided. The total distance traveled by the ship in three days is 900 km. Additionally, the distance traveled on the second and third days is twice as much as the distance traveled on the first day.

Let's denote the distance traveled on the first day as x km. According to the given information, the distance traveled on the second day is 2x km, and the distance traveled on the third day is also 2x km.

To find the total distance traveled, we can sum up the distances traveled on each day:

x + 2x + 2x = 900

Simplifying the equation:

5x = 900

Dividing both sides of the equation by 5:

x = 180

Therefore, the distance traveled on the first day is 180 km, the distance traveled on the second day is 2 * 180 = 360 km, and the distance traveled on the third day is also 2 * 180 = 360 km.

So, the ship traveled 180 km on the first day, 360 km on the second day, and 360 km on the third day.
