Question

На олимпийских играх в пекине победитель в беге на 400м пробежал дистанцию примерно за 40 секунд, а победитель в плаванье примерно за 4 минуты . во сколько раз бегун бежал быстрее , чем плыл пловец

Answer 1

Для начала устанавливаем скорость пловца и бегуна:
400/40=10 м/с-скорость бегуна
400/240≈1.7 м/с
Теперь вычитаем:
10-1.7=8.3 м/с

Answer 2

Calculation of Speed Difference between the Runner and Swimmer

To calculate the speed difference between the runner and the swimmer, we need to compare the time it took for each athlete to complete their respective events.

According to the information provided, the winner of the 400m race completed the distance in approximately 40 seconds, while the winner of the swimming event completed the race in approximately 4 minutes.

To find the speed difference, we can convert the time taken by the swimmer to seconds. Since there are 60 seconds in a minute, 4 minutes is equal to 4 * 60 = 240 seconds.

Now, we can calculate the speed difference:

Speed Difference = Runner's Speed / Swimmer's Speed

The runner's speed can be calculated by dividing the distance (400m) by the time taken (40 seconds):

Runner's Speed = 400m / 40s = 10m/s

The swimmer's speed can be calculated by dividing the distance (unknown) by the time taken (240 seconds):

Swimmer's Speed = Distance / 240s

Therefore, the speed difference can be calculated as:

Speed Difference = 10m/s / (Distance / 240s)

To find the speed difference, we need to know the distance covered by the swimmer. Unfortunately, the distance covered in the swimming event is not provided in the question. Without this information, we cannot accurately calculate the speed difference between the runner and the swimmer.

Please provide the distance covered by the swimmer in order to calculate the speed difference accurately.
