Question

Заполни таблицу. Составь и реши обратные задачи. Легкоатлет бежит со скоростью 100 м/мин. За какое время он преодолеет расстояние в 2 км? Скорость Время Расстояние

Answer 1

Ответ:

1км=1000м

2км=2000м

2000:100=20(мин.)

Answer 2

Ответ двадцать минут. Расстояние делишь на на скорость вот, и все

Answer 3

Sure, here's the completed table:

Скорость (м/мин)	Время (мин)	Расстояние (м)
100	20	2000

In this example, the athlete runs at a speed of 100 meters per minute. To find the time it takes to cover a distance of 2 kilometers, we can use the formula:

Time = Distance / Speed

Plugging in the values: Time = 2000 meters / 100 meters/minute = 20 minutes

Now, let's create and solve some inverse problems based on this information:

Inverse Problem 1: If the athlete wants to cover a distance of 3000 meters at the same speed, how long will it take?

Solution: Using the same formula: Time = Distance / Speed Time = 3000 meters / 100 meters/minute = 30 minutes

So, it will take the athlete 30 minutes to cover a distance of 3000 meters at a speed of 100 meters per minute.

Inverse Problem 2: If the athlete wants to cover a distance of 1500 meters in 15 minutes, what should be their speed?

Solution: Rearranging the formula to solve for speed: Speed = Distance / Time Speed = 1500 meters / 15 minutes = 100 meters/minute

So, the athlete needs to run at a speed of 100 meters per minute to cover a distance of 1500 meters in 15 minutes.
