Answer 1

1)(0.5+0.5):60=1\60ч=1мин-потребуется.

Answer 2

0,5+0,5=1км нужно пройти растояние
1:60=1/60ч=1мин потребуется поезду пройти путь

Answer 3

Problem Analysis

To solve this problem, we need to find the time it takes for a train to pass through a tunnel. We are given the length of the train, the speed of the train, and the length of the tunnel. We can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for the train to pass through the tunnel.

Calculation

Given: - Length of the train = 0.5 km - Speed of the train = 60 km/h - Length of the tunnel = 0.5 km

To find the time it takes for the train to pass through the tunnel, we need to calculate the total distance the train travels, which is the sum of the length of the train and the length of the tunnel.

Total distance = Length of the train + Length of the tunnel

Total distance = 0.5 km + 0.5 km = 1 km

Now, we can use the formula:

Time = Total distance / Speed

Time = 1 km / 60 km/h

To simplify the calculation, let's convert the speed from km/h to km/min. Since there are 60 minutes in an hour, we divide the speed by 60.

Speed = 60 km/h / 60 = 1 km/min

Now we can calculate the time:

Time = 1 km / 1 km/min = 1 min

Therefore, it will take the train 1 minute to pass through the tunnel.

Answer

The train will take 1 minute to pass through the tunnel.

Please note that the above calculation assumes a constant speed throughout the journey and does not account for acceleration or deceleration.
