швидкість час відстаньвелосипед.12 км/год ? 30км ? вершник 12 км/год ?Пожалуйста решите только бистро

Answer 1

Якщо велосипедист їде зі швидкістю 12 км. за годину, тоді 60:12=5 . Один км. він їде 5 хвилин. 30х5=150. Значить 150 хвилин є 2 години 30 хвилин. Велосипедист проїде 30 км. за 2 години 30 хвилин

Answer 2

Calculation of Time and Distance for a Bicycle

To calculate the time and distance for a bicycle traveling at a speed of 12 km/h, we can use the formula:

Time = Distance / Speed

Let's calculate the time it would take for the bicycle to travel a distance of 30 km at a speed of 12 km/h.

Distance = 30 km Speed = 12 km/h

Using the formula, we can calculate the time:

Time = 30 km / 12 km/h

Calculating this, we find that the time it would take for the bicycle to travel a distance of 30 km at a speed of 12 km/h is 2.5 hours.

Now, let's consider a rider traveling at a speed of 12 km/h. If the rider covers a distance of 12 km, we can calculate the time it would take using the same formula:

Distance = 12 km Speed = 12 km/h

Time = 12 km / 12 km/h

Calculating this, we find that the time it would take for the rider to cover a distance of 12 km at a speed of 12 km/h is 1 hour.

Please note that these calculations assume a constant speed throughout the journey and do not take into account factors such as breaks, terrain, or changes in speed.
