Question

Поезд проходит расстояние между двумя станциями за 4,2 ч двигаясь со скоростью 54км/ч .за какое время он пройдёт это расстояние если будет двигаться со скоростью 63км/ч

Answer 1

1) 54 х 4,2 = 226,8 (км)  - расстояние
2) 226,8 / 63 = 3,6 (ч)

Answer 2

Calculation of Time to Travel Distance

To calculate the time it takes for a train to travel a certain distance, we can use the formula:

Time = Distance / Speed

Given that the train is traveling at a speed of 54 km/h and needs to cover a distance between two stations, we can calculate the time it takes using the above formula.

Let's assume the distance between the two stations is D.

When the train is moving at a speed of 54 km/h, the time it takes to cover the distance D is:

Time1 = D / 54

Now, let's assume the train increases its speed to 63 km/h. The time it takes to cover the same distance D at this speed is:

Time2 = D / 63

To find the difference in time between the two scenarios, we can subtract Time1 from Time2:

Time Difference = Time2 - Time1

Let's calculate the time difference:

Time Difference = (D / 63) - (D / 54)

Now, we can simplify the equation:

Time Difference = D * (1/63 - 1/54)

To find the value of D, we need more information or assumptions about the distance between the two stations. Could you please provide the distance between the two stations?
