Question

Мотоциклист проехал 18 км за 30 минут.Какое расстояние он проедет за 3 часа???

Answer 1

30 минут это 30:60=0.5 часа

составим пропорцию
18 км 0.5 часа
  х км 3 часа
х=18*3:0.5=108 км

Ответ: 108 км

Answer 2

Calculating the Distance Traveled by the Motorcyclist

To calculate the distance the motorcyclist will travel in 3 hours, we can use the formula: distance = speed × time

Given that the motorcyclist traveled 18 km in 30 minutes, we can first calculate the speed: speed = distance / time

The speed of the motorcyclist can be calculated as: speed = 18 km / 0.5 hours (since 30 minutes is half an hour)

Let's calculate the speed first and then use it to find the distance traveled in 3 hours.

Calculating the Speed

The speed of the motorcyclist can be calculated as: speed = 18 km / 0.5 hours

Using this formula, we find that the speed of the motorcyclist is 36 km/h.

Calculating the Distance Traveled in 3 Hours

Now that we have the speed, we can calculate the distance the motorcyclist will travel in 3 hours: distance = speed × time

Substituting the values, we get: distance = 36 km/h × 3 hours

Calculating this, we find that the motorcyclist will travel a distance of 108 km in 3 hours.
