Question

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

Answer 1

В первый час автобус прошел 0.3125 - ую часть пути (30/96) 
Во второй час 0,25 - ую часть пути (24/96) (четверть)
В третий час  0,4375 - ую часть пути (42/96) 

Answer 2

Calculation of the Distance Traveled by the Bus in Each Hour

To calculate the fraction of the total distance traveled by the bus in each hour, we need to determine the distance traveled in each hour and divide it by the total distance.

Given the following distances traveled by the bus in each hour: - First hour: 30 km - Second hour: 24 km - Third hour: 42 km

To calculate the fraction of the total distance traveled by the bus in each hour, we can use the following formula:

Fraction of distance traveled = Distance traveled in the hour / Total distance

Let's calculate the fractions for each hour:

1. First hour: - Distance traveled: 30 km - Total distance: 30 km - Fraction of distance traveled: 30 km / 30 km = 1

2. Second hour: - Distance traveled: 24 km - Total distance: 30 km + 24 km = 54 km - Fraction of distance traveled: 24 km / 54 km ≈ 0.4444

3. Third hour: - Distance traveled: 42 km - Total distance: 30 km + 24 km + 42 km = 96 km - Fraction of distance traveled: 42 km / 96 km ≈ 0.4375

Therefore, the bus traveled the following fractions of the total distance in each hour: - First hour: 1 - Second hour: approximately 0.4444 - Third hour: approximately 0.4375

Please note that the fractions for the second and third hours are approximate values rounded to four decimal places.
