Question

В первый час автобус проехал2/5всего пути во второй час 1/3 пути а в третий остальные28 Какое расстояние проехал автобус за эти 3 часа?

Answer 1

2/5 и 1/3 подведем к общему знаменателю 15
6/15 в первый час
5/15 во второй час
6/15+5/15=11/15
1 - 11/15=4/15 прошёл в третий час
4/15 пути = 28
28÷4×15=105 км проехал автобус за 3 часа

Answer 2

Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus in the given three hours, we need to add up the distances covered in each hour.

In the first hour, the bus traveled 2/5 of the total distance. In the second hour, the bus traveled 1/3 of the total distance. In the third hour, the bus traveled the remaining 28 units of distance.

To find the total distance traveled, we can add up these three distances.

Calculation:

Distance traveled in the first hour: 2/5 of the total distance Distance traveled in the second hour: 1/3 of the total distance Distance traveled in the third hour: 28 units of distance

Let's calculate the total distance traveled by the bus:

1. Distance traveled in the first hour: 2/5 of the total distance 2. Distance traveled in the second hour: 1/3 of the total distance 3. Distance traveled in the third hour: 28 units of distance

To find the total distance, we can add up these three distances:

Total distance = (Distance in the first hour) + (Distance in the second hour) + (Distance in the third hour)

Let's substitute the given values into the equation:

Total distance = (2/5) + (1/3) + 28

To simplify the calculation, we can convert the fractions to a common denominator:

Total distance = (6/15) + (5/15) + 28

Now, let's add up the fractions:

Total distance = (6 + 5)/15 + 28

Total distance = 11/15 + 28

To add the fractions, we need to find a common denominator:

Total distance = (11 + 28*15)/15

Total distance = (11 + 420)/15

Total distance = 431/15

Therefore, the total distance traveled by the bus in the given three hours is 431/15 units.

Please note that the given question does not provide the units of distance, so we cannot determine the exact distance in specific units. However, we have calculated the distance in terms of a fraction.
