Question

Туристы прошли 54 км за три дня. За первый день они прошли 7/18 пути, за второй - 2/9 всего пути. Какое расстояние прошли туристы за третий день?

Answer 1

1) 54:18*7=21км прошли туристы в 1 день.
2) 54:9*2=12км прошли во 2 день.
3) 54-(21+12)=21км прошли за 3 день.

Answer 2

54*7/18=21 км прошли туристы в первый день
54*2/9=12 км прошли туристы за второй день
12+21=33 км прошли туристы за первые два дня
54-33=21 км прошли туристы за третий день

Answer 3

Calculation of Distance Covered by Tourists

To calculate the distance covered by the tourists on the third day, we need to determine the remaining distance after the first two days.

The tourists covered a total distance of 54 km in three days. On the first day, they covered 7/18 of the total distance, and on the second day, they covered 2/9 of the total distance.

Let's calculate the distance covered on the third day:

1. Calculate the distance covered on the first day: - Distance covered on the first day = (7/18) * Total distance - Distance covered on the first day = (7/18) * 54 km

2. Calculate the distance covered on the second day: - Distance covered on the second day = (2/9) * Total distance - Distance covered on the second day = (2/9) * 54 km

3. Calculate the remaining distance after the first two days: - Remaining distance = Total distance - Distance covered on the first day - Distance covered on the second day

4. Calculate the distance covered on the third day: - Distance covered on the third day = Remaining distance

Let's perform the calculations:

1. Distance covered on the first day: - Distance covered on the first day = (7/18) * 54 km - Distance covered on the first day = 21 km

2. Distance covered on the second day: - Distance covered on the second day = (2/9) * 54 km - Distance covered on the second day = 12 km

3. Remaining distance after the first two days: - Remaining distance = 54 km - 21 km - 12 km - Remaining distance = 21 km

Therefore, the tourists covered 21 km on the third day.
