Question

В первый день мотоциклист проехал четыре седьмых длины всего маршрута, а за второй день 15% оставшегося расстояния, после чего им осталось проехать 76, 5 км. Какова длина наименьшего маршрута?(решите пожалуйста с объяснением, а не просто ответ) за решение даю 10 пунктов, а кто правильно ответит, я переправлю еще 20 пунктов, хорошо?

Answer 1

Пусть протяженность всего маршрута равна "х". За первый день проехал четыре седьмых икс- осталось три седьмых икс. За второй день проехал 15% оставшегося растояния- осталось - 85% - а это 76,5 км.

Значит 0,85*(три седьмых икс)=76,5

 

Отсюда "х"=210 км

 

Ура!

Answer 2

Calculating the Length of the Shortest Route

To calculate the length of the shortest route, we can follow these steps:

1. Calculate the Distance Traveled on the First Day: - On the first day, the motorcyclist traveled four sevenths of the total route length.

2. Calculate the Distance Traveled on the Second Day: - On the second day, the motorcyclist traveled 15% of the remaining distance, leaving 76.5 km to travel.

3. Determine the Total Distance: - Using the information from the first and second days, we can calculate the total distance of the route.

4. Calculate the Length of the Shortest Route: - With the total distance known, we can find the length of the shortest route.

Let's proceed with the calculations.

Step 1: Calculate the Distance Traveled on the First Day

The motorcyclist traveled four sevenths of the total route length on the first day.

Step 2: Calculate the Distance Traveled on the Second Day

On the second day, the motorcyclist traveled 15% of the remaining distance, leaving 76.5 km to travel.

Step 3: Determine the Total Distance

To calculate the total distance, we need to combine the distance traveled on the first day with the remaining distance after the second day.

The total distance can be calculated using the following formula: Total Distance = Distance Traveled on First Day + Remaining Distance after Second Day

Step 4: Calculate the Length of the Shortest Route

Once we have the total distance, we can determine the length of the shortest route.

Let's proceed with the calculations to find the length of the shortest route.
