Question

Турист преодолевал маршрут три дня. в первый день он прошёл три десятые км всего маршрута, а во второй день семь восьмых км, пройденых в первый день. какого протяженность трехдневного маршрута, если во второй день он прошёл 21 км

Answer 1

1)21/7*8=24(км)-прошел в первый день
2)24/3*10=80(км)

Answer 2

Calculating the Total Distance of the Three-Day Route

To calculate the total distance of the three-day route, we can use the information provided about the distances covered on the first and second days.

1. Distance Covered on the First Day: - On the first day, the tourist covered three-tenths (3/10) of the total route.

2. Distance Covered on the Second Day: - On the second day, the tourist covered seven-eighths (7/8) of the distance covered on the first day, which is equivalent to 21 km.

Calculation

To find the total distance of the three-day route, we can use the information provided about the distances covered on the first and second days.

Let's denote the total distance of the route as D.

According to the given information: - Distance covered on the first day = 3/10 * D - Distance covered on the second day = 7/8 * (3/10 * D) = 21 km

We can use this information to solve for the total distance D.

Solution

First, we calculate the distance covered on the first day: - Distance covered on the first day = 3/10 * D

Then, we calculate the distance covered on the second day: - Distance covered on the second day = 7/8 * (3/10 * D) = 21 km

Now, we can solve for the total distance D: - 7/8 * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) = 21 - (21/8) * (3/10 * D) =
