Question

Автомобиль проехал 20 км, а автобус проехал в 2 раза больше. Сколько времени потратил автобус, если ехал со скоростью 50км/ч?

Answer 1

1) 2 × 20 = 40 км - проехал автобус
2) 40 ÷ 50 = 0, 8 ч - был в пути автобус
60 мин × 0,8 = 48 минут
Ответ : автобус был в пути 48 минут.

Answer 2

Calculation of Time Spent by the Bus

To calculate the time spent by the bus, we need to determine the distance it traveled. We are given that the car traveled 20 km and the bus traveled twice as much. Therefore, the distance traveled by the bus is 20 km * 2 = 40 km.

Next, we can use the formula: time = distance / speed to calculate the time spent by the bus. The speed of the bus is given as 50 km/h.

Using the formula, we have:

time = distance / speed time = 40 km / 50 km/h

To simplify the calculation, we can convert the speed from km/h to km/min by dividing it by 60:

50 km/h / 60 = 5/6 km/min

Now, we can calculate the time spent by the bus:

time = 40 km / (5/6 km/min)

To divide by a fraction, we can multiply by its reciprocal:

time = 40 km * (6/5 min/km) time = 240/5 min time = 48 min

Therefore, the bus spent 48 minutes traveling a distance of 40 km at a speed of 50 km/h.
