Question

Самолёт пролетел 1840 км за 2 ч причём за первый час он пролетел на 28 км больше чем за второй . Сколько километров пролетел самолёт за второй час

Answer 1

Х+(х+28)=1840
2х+28=1840
2х=1840-28
2х=1812
х=1812:2
х=906

Answer 2

1)1840:2+28=948(км)- пролетел самолёт за первый час
2) 1840-948=892(км)-пролетел самолёт за второй час
Ответ: 892 км

Answer 3

Calculation of Distance Traveled by the Plane

To calculate the distance traveled by the plane in the second hour, we can use the information given in the question.

According to the question, the plane flew a total distance of 1840 km in 2 hours. Additionally, it flew 28 km more in the first hour than in the second hour.

Let's denote the distance traveled in the second hour as x km.

Based on the given information, we can set up the following equation:

x + (x + 28) = 1840

Simplifying the equation:

2x + 28 = 1840

2x = 1840 - 28

2x = 1812

x = 906

Therefore, the plane traveled 906 km in the second hour.
