Question

Автобус выехал с автовокзала в 12 часов 30 минут с секундами и, двигаясь без остановок, приехал в поселок в 13 часов 10 минут с секундами, поддерживая на протяжении всего пути скорость в интервале от 42 км/ч до 48 км/ч. Каким мог быть пройденный автобусом путь? Ответ выразите в километрах, округлив до десятых.

Answer 1

13 часов 10 минут с секундами -  12 часов 30 минут с секундами = 40 минут движения 

минимально ресстояние он мог проехать 42*2/3=28 км .. 

а мааксимальное 48*2/3=32 км 

ответ от 28 до 32

Answer 2

ехал  40 минут=2/3 часа ( с 12 ч30 мин до 13 ч 10 мин)

 42* 2/3= 28км 

48 *2\3=32 км

ответ проиденный путь может быть от 28 до 32 км

Answer 3

Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus, we need to determine the time it took for the bus to travel from the bus station to the village and the average speed maintained during the journey.

The bus departed from the bus station at 12:30:00 and arrived at the village at 13:10:00. The total time taken for the journey can be calculated by subtracting the departure time from the arrival time:

13:10:00 - 12:30:00 = 0 hours 40 minutes 0 seconds

Next, we need to calculate the average speed of the bus during the journey. The speed of the bus ranged from 42 km/h to 48 km/h throughout the entire journey.

To find the average speed, we can take the average of the minimum and maximum speeds:

(42 km/h + 48 km/h) / 2 = 45 km/h

Now, we can calculate the distance traveled by the bus using the formula:

Distance = Speed × Time

Converting the time taken for the journey to hours:

0 hours 40 minutes 0 seconds = 0.67 hours

Substituting the values into the formula:

Distance = 45 km/h × 0.67 hours

Calculating the distance:

Distance = 30.15 km

Therefore, the distance traveled by the bus is approximately 30.15 kilometers.
