Question

Поезд двигался со скоростью 70 км/ч и преодолел путь за 3 часа . за сколько он пройдет тот же путь если будет двигаться со скоростью 55км ч

Answer 1

70км/ч•3ч=210 км- длина пути
210км:55=3.8181818...

Answer 2

Calculating Time and Speed

To calculate the time it takes to travel a certain distance at a given speed, you can use the formula:

time = distance / speed

Given that the train traveled at a speed of 70 km/h and covered the distance in 3 hours, we can calculate the distance using the formula:

distance = speed * time

Substituting the given values: distance = 70 km/h * 3 h = 210 km

Calculating Time for a Different Speed

Now, if the train were to travel at a speed of 55 km/h, we can calculate the time it would take to cover the same distance using the formula:

time = distance / speed

Substituting the distance of 210 km and the new speed of 55 km/h: time = 210 km / 55 km/h ≈ 3.82 hours

So, the train would take approximately 3.82 hours to cover the same distance at a speed of 55 km/h
