Question

Велосипедист едет по прямому шоссе с собственной скоростью 18 км.ч.с какой скоростью будет ехать велосипедист,если ему в спину будет дуть ветер со скоростью 5 м.с?А если ветер будет дуть в лицо,какой будет скорость велосипедиста?

Answer 1

1 м/с=3.6 км/час
5 м/с=18км/час
1)18+18=36 км/час - скорость с ветром в спину
2)18-18=0км/час - скорость против ветра

Answer 2

Calculation of the Cyclist's Speed with Tailwind

When a cyclist is riding on a straight road with their own speed and there is a tailwind blowing in their direction, the wind speed adds to the cyclist's speed. To calculate the cyclist's speed with a tailwind, we need to add the wind speed to the cyclist's own speed.

Given: - Cyclist's own speed: 18 km/h - Wind speed: 5 m/s

To calculate the cyclist's speed with a tailwind, we need to convert the wind speed from meters per second to kilometers per hour. We can use the conversion factor of 1 m/s = 3.6 km/h.

Converting the wind speed: 5 m/s * 3.6 km/h = 18 km/h

Now, we can add the wind speed to the cyclist's own speed: Cyclist's speed with tailwind = Cyclist's own speed + Wind speed Cyclist's speed with tailwind = 18 km/h + 18 km/h = 36 km/h

Therefore, if there is a tailwind blowing at a speed of 5
