От поселка до города автобус проезжает 144 км со средней скоростью 48 км/ч и делает две десятиминутные остановки . Электричка от поселка до города проезжает 135 км со средней скоростью 54 км/ч и делает пять пятиминутных остановке на промежуточных станциях . На каком транспорте быстрее добираться до города?

Answer 1

1) 144:48=3 часа +10*2=20=3ч 20мин едет автобус
2) 135:54=2, 5 часа +5*5=25=2часа 55мин едет электричка
3) 3 ч 20 мин > 2 ч 55 мин
Ответ: на электричке быстрее.

Answer 2

Comparison of Bus and Train Travel Times

To determine which mode of transportation is faster for traveling from the village to the city, let's compare the travel times of the bus and the train.

The bus travels a distance of 144 km with an average speed of 48 km/h. It makes two ten-minute stops along the way.

The train, on the other hand, covers a distance of 135 km with an average speed of 54 km/h. It makes five five-minute stops at intermediate stations.

To calculate the travel time for each mode of transportation, we can use the formula:

Travel Time = Distance / Speed

For the bus: - Travel Time = 144 km / 48 km/h = 3 hours

Considering the two ten-minute stops, the total travel time for the bus would be slightly longer.

For the train: - Travel Time = 135 km / 54 km/h = 2.5 hours

Taking into account the five five-minute stops, the total travel time for the train would also be slightly longer.

Therefore, based on the given information, it appears that the train is faster for traveling from the village to the city.

Please note that these calculations are based on the provided information and do not take into account other factors such as traffic conditions or delays.
