Question

В течение 0,5 мин поезд двигался равномерно со скоростью 54 км/ч. Какой путь он прошёл за это время?

Answer 1

Ответ:450

Объяснение: рассчитал сколько времени на 1 метр и умножал методом подбора

Answer 2

Calculating the Distance Traveled by the Train

To calculate the distance traveled by the train, we can use the formula:

Distance = Speed × Time

Given that the train was moving at a constant speed of 54 km/h for 0.5 minutes, we need to convert the time to hours before using the formula.

Conversion of Time from Minutes to Hours

To convert 0.5 minutes to hours, we can use the fact that 1 hour is equal to 60 minutes. Therefore, 0.5 minutes is equal to 0.5/60 hours.

Converting 0.5 minutes to hours: 0.5 minutes = 0.5/60 hours

Calculating the Distance Traveled

Now, we can use the formula to calculate the distance traveled by the train:

Distance = Speed × Time

Substituting the given values: Distance = 54 km/h × 0.5/60 h

Calculating the distance: Distance = 54 km/h × 0.5/60 h = 0.45 km

So, the train traveled a distance of 0.45 kilometers in 0.5 minutes at a constant speed of 54 km/h.
