Question

От поселка до города автобус проезжает 144 км со средней скоростью 48 км ч и делает десятиминутные остановки электричка от поселка до города приезжает 135 км со средней скоростью 54 км ч и делает пятиминутных остановок на промежуточных станциях На каком транспорте быстрее добираться до города ?

Answer 1

1) 144/48=3 часа 2) 2*10=20мин 3) 3 часа+20 мин=3часа20мин (автобус)
4) 135/54=2часа 30 мин 5) 5*5=25мин 6) 2часа30мин+25мин=2часа55мин (электричка)
7) 3часа20мин - 2часа55мин = 25мин
Ответ: Электричка едет быстрее на 25мин

Answer 2

Comparing Bus and Train Travel to the City

To determine which mode of transportation is faster, we can compare the time it takes for the bus and the train to travel from the village to the city.

Bus Journey: - Distance: 144 km - Average Speed: 48 km/h - 10-minute stops

Train Journey: - Distance: 135 km - Average Speed: 54 km/h - 5-minute stops at intermediate stations

Calculating Travel Time

Let's calculate the travel time for each mode of transportation.

Bus Travel Time: - Time = Distance / Speed = 144 km / 48 km/h = 3 hours

Train Travel Time: - Time = Distance / Speed = 135 km / 54 km/h = 2.5 hours

Including Stoppage Time

Now, let's include the stoppage time for each mode of transportation.

Bus Total Travel Time: - Stoppage Time = 10 minutes - Total Time = 3 hours + 10 minutes = 3 hours 10 minutes

Train Total Travel Time: - Stoppage Time = 5 minutes - Total Time = 2.5 hours + 5 minutes = 2 hours 35 minutes

Conclusion

Based on the calculations, the train is faster for traveling from the village to the city, taking approximately 2 hours and 35 minutes compared to the bus, which takes approximately 3 hours and 10 minutes. Therefore, the train is faster for traveling to the city.
