Question

Решить задачу за три дня похода на байдарках школьники про плыли 90 км. В первый день они проплыли 43 км, что на 14 км больше, чем во второй. сколько километров про плыли школьники в третий день похода.

Answer 1

43 − 14 = 29км проплыли во второй день
43 + 29 = 72 км  проплыли в первый и во второй дни
90 − 72 = 18 км проплыли школьники в третий день похода

Answer 2

Problem Analysis

The problem states that a group of schoolchildren went on a kayaking trip for three days and covered a total distance of 90 km. On the first day, they paddled 43 km, which was 14 km more than the distance they paddled on the second day. We need to determine the distance they paddled on the third day.

Solution

Let's assume that the distance paddled on the second day is x km. According to the problem, the distance paddled on the first day is 14 km more than the distance paddled on the second day. Therefore, we can write the equation:

Distance on the first day = Distance on the second day + 14

Substituting the given values, we have:

43 km = x km + 14 km

Simplifying the equation, we find:

x km = 43 km - 14 km x km = 29 km

So, the distance paddled on the second day is 29 km.

To find the distance paddled on the third day, we subtract the sum of the distances paddled on the first and second days from the total distance of 90 km:

Distance on the third day = Total distance - (Distance on the first day + Distance on the second day) Distance on the third day = 90 km - (43 km + 29 km) Distance on the third day = 90 km - 72 km Distance on the third day = 18 km

Therefore, the schoolchildren paddled 18 km on the third day of the kayaking trip.

Answer

The schoolchildren paddled 18 km on the third day of the kayaking trip.
