Question

Велосипедист, двигаясь под уклон, проходит путь 100 м за 10с. Скатившись с него, он проезжает до остановки ещё 0,6 км за 1 мин. Какова средняя скорость велосипедиста на всём пути?

Answer 1

Средняя скорость то весь путь делить на все время. Vср=sобщ/T(общ) s=700 m t= 70 c vср= 700/70=10

Answer 2

Calculation of Average Speed

To calculate the average speed of the cyclist on the entire journey, we need to determine the total distance traveled and the total time taken.

1. Distance traveled on the slope: - The cyclist covers a distance of 100 meters in 10 seconds.

2. Distance traveled after rolling down: - The cyclist travels an additional distance of 0.6 kilometers (or 600 meters) in 1 minute.

To calculate the total distance traveled, we need to convert the distance traveled after rolling down from kilometers to meters: - 0.6 kilometers is equal to 600 meters.

Therefore, the total distance traveled is: - Distance on the slope: 100 meters - Distance after rolling down: 600 meters - Total distance: 100 meters + 600 meters = 700 meters

To calculate the total time taken, we need to convert the time taken after rolling down from minutes to seconds: - 1 minute is equal to 60 seconds.

Therefore, the total time taken is: - Time on the slope: 10 seconds - Time after rolling down: 60 seconds - Total time: 10 seconds + 60 seconds = 70 seconds

Now, we can calculate the average speed using the formula: Average Speed = Total Distance / Total Time

Substituting the values: Average Speed = 700 meters / 70 seconds

Calculation:

To calculate the average speed, we divide the total distance of 700 meters by the total time of 70 seconds:

Average Speed = 700 meters / 70 seconds = 10 meters per second

Therefore, the average speed of the cyclist on the entire journey is 10 meters per second.
