Question

Машина проехала 56 км за 30 минут. Сколько километров проедет велосипедист за 2 ч, если его скорость составляет одну четвертую скорости машины?

Answer 1

30 минут = 0,5 часа
найдём скорость
56*0,5=112 км/ч
скорость велосипедиста 1/4 от машины
112/4=28 км/ч
найдём расстояние
28*2= 56 км

Answer 2

Calculating the Distance Traveled by the Bicyclist

To calculate the distance the bicyclist will travel in 2 hours, we can use the information provided about the car's speed and distance traveled.

Given: - The car traveled 56 km in 30 minutes.

First, let's calculate the car's speed: - Speed = Distance / Time - Speed = 56 km / 0.5 hours - Speed = 112 km/h

Now, we need to find one-fourth of the car's speed: - One-fourth of the car's speed = 112 km/h / 4 - One-fourth of the car's speed = 28 km/h

Next, we can calculate the distance the bicyclist will travel in 2 hours at one-fourth of the car's speed.

Calculating the Distance Traveled by the Bicyclist

The distance traveled by the bicyclist can be calculated using the formula: - Distance = Speed × Time

Using the given speed of one-fourth of the car's speed (28 km/h) and the time of 2 hours: - Distance = 28 km/h × 2 hours - Distance = 56 km

Therefore, the bicyclist will travel 56 kilometers in 2 hours at a speed of one-fourth of the car's speed.
