Question

1час-40%. 2 час-25%. 3 час-28КМРасстояние-?

Answer 1

Пошаговое объяснение:

1) 40%=40/100=2/5 пути проехал в первый час

2) 2/5+1/3 =6/15+5/15=11/15 пути проехал за 1 и 2 часы

3) 1-11/15=15/15-11/15=4/15 пути проехал за 3 час что 28 км

4) 28÷4/15=28÷4×15=105 км проехал автобус за все 3 часа

Вот решение

Answer 2

To calculate the distance traveled, we need to find the distance covered in each hour and then sum them up.

For the first hour, 40% of the distance is covered. So, 40% of the total distance is:

40% = 0.40

For the second hour, 25% of the distance is covered. So, 25% of the total distance is:

25% = 0.25

For the third hour, 28 km are covered.

Let's calculate the distance covered in each hour:

First hour: 0.40 * Distance = 40% * Distance Second hour: 0.25 * Distance = 25% * Distance Third hour: 28 km

The total distance traveled is the sum of these distances:

Total Distance = (40% * Distance) + (25% * Distance) + 28 km

Since we don't have the actual value of the total distance, we can express it as a variable, let's say D:

Total Distance = (0.40 * D) + (0.25 * D) + 28 km

Simplifying this expression:

Total Distance = 0.65D + 28 km

Therefore, the distance traveled is 0.65 times the total distance plus 28 kilometers.
