Question

Помогите пожалуйста 4. Мальчик преодолевает на велосипеде расстояние 3 000 м за 10 мин. С какой средней скоростью едет мальчик на велосипеде в м/с и км/ч​

Answer 1

Пошаговое объяснение:

1)10 минут = 600 секунд

скорость = 3000/600=50м/с

Answer 2

Ответ:

5 м/сек или 18 км/ч

Пошаговое объяснение:

V=S/t

V=3000:10=300 м/мин

1 мин=60 сек

V=300:60=5 м/сек

1 км=1000 м

1 час=60 мин

60/1000=0,06

V=300*0,06=18 км/ч

Answer 3

Calculating Average Speed

To calculate the average speed of the boy on the bicycle, we can use the formula:

Average Speed = Total Distance / Total Time

Given: - Total Distance = 3,000 m - Total Time = 10 min

First, let's convert the total time from minutes to hours: - 10 minutes = 10/60 hours = 1/6 hours

Now, we can calculate the average speed in meters per second (m/s) and kilometers per hour (km/h).

Calculations

Average Speed in m/s: - Average Speed = 3,000 m / (1/6) hours - Average Speed = 3,000 m / 0.1667 hours - Average Speed ≈ 18,000 m/h - Average Speed ≈ 18,000 m/h ÷ 3,600 s/h (1 hour = 3,600 seconds) - Average Speed ≈ 5 m/s

Average Speed in km/h: - Average Speed = 3,000 m / (1/6) hours - Average Speed = 3,000 m / 0.1667 hours - Average Speed ≈ 18,000 m/h - Average Speed ≈ 18,000 m/h ÷ 1,000 m/km - Average Speed ≈ 18 km/h

So, the boy's average speed on the bicycle is approximately 5 m/s and 18 km/h.
