Question

Автобус прошёл за 4 часа 180 км в 1 час он прошёл 4\15 всего пути во 2 час 13\16 того, что прошёл в 1 час, в 3 час вдвое меньше того что прошёл за первие 2 часа и в 4 час остальное. сколько км прошёл автобус в 4 час

Answer 1

1) 180*4\15 = 48 (км) - за 1 час
2) 48*13\16 = 39 (км) - за 2 час 
3) (48+39):2 = 43,5 (км) - за 3-й час
4) 180 - (48+39+43,5) = 49,5 (км)- за 4 час

Answer 2

Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus in 4 hours, we need to break down the information provided.

According to the given information: - In the first hour, the bus traveled 4/15 of the total distance. - In the second hour, the bus traveled 13/16 of what it traveled in the first hour. - In the third hour, the bus traveled half of what it traveled in the first two hours. - In the fourth hour, the bus traveled the remaining distance.

Let's calculate the distance step by step:

1. Calculate the distance traveled in the first hour: - The bus traveled 180 km in 4 hours. - Therefore, in the first hour, it traveled 180 km * (4/15) = 48 km.

2. Calculate the distance traveled in the second hour: - The bus traveled 13/16 of what it traveled in the first hour. - Therefore, in the second hour, it traveled 48 km * (13/16) = 39 km.

3. Calculate the distance traveled in the third hour: - The bus traveled half of what it traveled in the first two hours. - Therefore, in the third hour, it traveled (48 km + 39 km) / 2 = 43.5 km.

4. Calculate the distance traveled in the fourth hour: - The bus traveled the remaining distance. - Therefore, in the fourth hour, it traveled 180 km - (48 km + 39 km + 43.5 km) = 49.5 km.

Therefore, the bus traveled 49.5 km in the fourth hour.
