Question

Автобус в первиый час прошёл 30 км. , во второй 24км. , а в третий 42км. Какую часть всего пути прошёл автобус в каждый день? Какую часть пути, оставшуюся после первого часа движения прошёл автобус во второй час и какую в третий?

Answer 1

30+24+42=96
$\frac{30}{96}$
$\frac{2}{96}$
$\frac{42}{96}$
96-30=66
$\frac{24}{66}$
$\frac{42}{66}$

Answer 2

Calculation of the Total Distance Traveled by the Bus Each Day

To calculate the total distance traveled by the bus each day, we need to add up the distances traveled in each hour.

In the first hour, the bus traveled 30 km. In the second hour, the bus traveled 24 km. In the third hour, the bus traveled 42 km.

To find the total distance traveled by the bus each day, we add up these distances: 30 km + 24 km + 42 km = 96 km.

Therefore, the bus traveled a total of 96 km each day.

Calculation of the Proportion of the Total Distance Traveled in Each Hour

To calculate the proportion of the total distance traveled by the bus in each hour, we need to divide the distance traveled in each hour by the total distance traveled each day.

Let's calculate the proportions for each hour:

- First hour: 30 km / 96 km = 0.3125 or 31.25% of the total distance. - Second hour: 24 km / 96 km = 0.25 or 25% of the total distance. - Third hour: 42 km / 96 km = 0.4375 or 43.75% of the total distance.

Therefore, the bus traveled 31.25% of the total distance in the first hour, 25% in the second hour, and 43.75% in the third hour.

Calculation of the Remaining Distance After the First Hour

To calculate the remaining distance after the first hour, we subtract the distance traveled in the first hour from the total distance.

Total distance: 96 km Distance traveled in the first hour: 30 km

Remaining distance after the first hour: 96 km - 30 km = 66 km.

Therefore, the bus traveled 66 km after the first hour.

Calculation of the Distance Traveled in the Second Hour and Third Hour

To calculate the distance traveled in the second hour and third hour, we need to subtract the distance traveled in the first hour from the total distance traveled in each hour.

Distance traveled in the second hour: 24 km - 30 km = -6 km. Distance traveled in the third hour: 42 km - 30 km = 12 km.

Therefore, the bus traveled -6 km in the second hour (which means it traveled 6 km in the opposite direction) and 12 km in the third hour.
