Question

В первый день турист преодолел 20 % намеченного пути,во второй день 3/7 всего пути,а в третий оставшиеся 13 км.Сколько км турист преодолел за три дня? ПОЖАЛУЙСТА

Answer 1

1 или 100% - весь путь
20%:100%=1/5 всего пути пройдено в 1 день
1/5+3/7=7/35+15/35=22/35 всего пути прошли за 2 дня
1-22/35=13/35 - прошли в 3 день
13:13*35=35 км турист прошёл за 3 дня

Answer 2

Calculating the Distance Traveled by the Tourist

To calculate the total distance the tourist traveled over three days, we can use the information provided:

1. Distance on the First Day: The tourist covered 20% of the planned distance. 2. Distance on the Second Day: The tourist covered 3/7 of the total distance. 3. Remaining Distance on the Third Day: The tourist had 13 km left to cover.

Calculation Steps

1. Calculate the total distance covered on the first day. 2. Calculate the total distance covered on the second day. 3. Add the distances covered on all three days to find the total distance traveled.

Calculation

1. Distance Covered on the First Day: - The total distance is represented by 100%. - The tourist covered 20% of the total distance. - Therefore, the distance covered on the first day is 20% of the total distance.

Calculation: 20% of the total distance

Result: The distance covered on the first day is 20% of the total distance.

2. Distance Covered on the Second Day: - The total distance is represented by 1 whole unit. - The tourist covered 3/7 of the total distance. - Therefore, the distance covered on the second day is 3/7 of the total distance.

Calculation: (3/7) * Total Distance

Result: The distance covered on the second day is 3/7 of the total distance.

3. Remaining Distance on the Third Day: - The tourist had 13 km left to cover on the third day.

Total Distance Traveled

To find the total distance traveled over three days, we need to add the distances covered on each day to the remaining distance on the third day.

Final Calculation

1. Total Distance Covered on the First Day: 20% of the total distance. 2. Total Distance Covered on the Second Day: 3/7 of the total distance. 3. Remaining Distance on the Third Day: 13 km.

Result: The total distance traveled by the tourist over three days can be calculated by adding the distances covered on each day to the remaining distance on the third day.

Let's calculate the total distance traveled.
