Question

От города до деревни дети 3 ч ехали на автобусе со скоростью 60км/ч. Обратный путь на автобусе занял 4 часа. С какой скоростью автобус ехал на обратном пути? У меня получается 60 км/ ч. Правильно?

Answer 1

1) 60*3=180 км расстояние между городом и деревней                                      2) 180:4=45 км/час скорость автобуса на обратном пути                                   Ответ: На обратном пути автобус ехал  со скоростью 45 км/час

Answer 2

Calculation of the Bus Speed on the Return Journey

To calculate the speed of the bus on the return journey, we can use the formula:

Speed = Distance / Time

In this case, the distance remains the same (since the bus traveled from the city to the village and then back to the city), but the time taken on the return journey is different.

Given that the bus took 3 hours to travel from the city to the village at a speed of 60 km/h, we can calculate the distance using the formula:

Distance = Speed × Time

Distance = 60 km/h × 3 h = 180 km

Now, on the return journey, the bus took 4 hours. To find the speed, we can use the same formula:

Speed = Distance / Time

Speed = 180 km / 4 h = 45 km/h

Therefore, the speed of the bus on the return journey was 45 km/h.

Please note that the calculation assumes a constant speed throughout the journey and does not account for factors such as traffic or stops along the way.
