Question

Помните пожалуйста решишь контрольную Туристический теплоход был в пути три дня. В первый день он прошел 210 км, что составило 35% всего пути , а во второй - 40% оставшегося расстояния. Сколько км прошел теплоход в третий день?

Answer 1

210:0,35=600км прошел за три дня
600-210=390км прошел за второй и третий день
390*0,4=156км прошел во второй день
390-156=234км прошел в третий день

Answer 2

Problem Analysis

We are given that a tourist ship was in transit for three days. On the first day, it covered 210 km, which is 35% of the total distance. On the second day, it covered 40% of the remaining distance. We need to determine how many kilometers the ship traveled on the third day.

Solution

Let's break down the problem step by step.

1. On the first day, the ship covered 35% of the total distance, which is 210 km. We can set up the following equation to find the total distance: ``` 0.35 * Total Distance = 210 km ``` Solving this equation, we find that the total distance is 600 km.

2. On the second day, the ship covered 40% of the remaining distance. The remaining distance can be calculated as follows: ``` Remaining Distance = Total Distance - Distance Covered on the First Day Remaining Distance = 600 km - 210 km = 390 km ``` The ship covered 40% of the remaining distance, which is 0.4 * 390 km = 156 km.

3. Finally, to find the distance covered on the third day, we subtract the distances covered on the first and second days from the total distance: ``` Distance Covered on the Third Day = Total Distance - Distance Covered on the First Day - Distance Covered on the Second Day Distance Covered on the Third Day = 600 km - 210 km - 156 km = 234 km ```

Therefore, the tourist ship traveled 234 km on the third day.

Answer

The tourist ship traveled 234 km on the third day.
