Question

Спортсмен на тренировке преодолевает 400 метров за половину минуты.Определите скорость спортсмена на данной дистанции. Ответ дайте в км/ч.

Answer 1

400м за 30сек⇒800м за 1мин
800*60/1000=48км/ч

Answer 2

Calculation of the Athlete's Speed

To determine the athlete's speed on the given distance, we need to convert the time taken to cover the distance into hours and calculate the speed in kilometers per hour.

Given: - Distance: 400 meters - Time: half a minute

To convert the time from minutes to hours, we divide it by 60: - Time in hours = 0.5 minutes / 60 = 0.0083 hours

To calculate the speed, we divide the distance by the time: - Speed = Distance / Time = 400 meters / 0.0083 hours

Calculating the speed: - Speed = 48,192 meters per hour

To convert the speed from meters per hour to kilometers per hour, we divide it by 1000: - Speed = 48,192 meters per hour / 1000 = 48.192 kilometers per hour

Therefore, the athlete's speed on the given distance is approximately 48.192 kilometers per hour.
