Question

Волк гонится за Зайцем. Сначала Заяц бежал 2 ч со скоростью 24 км/ч, затем он 3 ч ехал на велосипеде, а после этого 5 ч ехал на поезде со скоростью 48 км/ч. Всего Заяц пробежал и проехал 357 км. С какой скоростью он ехал на велосипеде? В таблице обязательно.

Answer 1

1. 1) 2*24 = 48 (км) - заяц пробежал
3. 2) 5*48 = 240(км) - заяц проехал на поезде.
5. 3)357-48-240 = 69(км) - заяц проехал на велосипеде.
7. 4)69:3=23(км/ч) - скорость на велосипеде.

Answer 2

Calculation of the Rabbit's Speed on a Bicycle

To determine the speed at which the rabbit was traveling on a bicycle, we need to analyze the given information.

According to the information provided, the rabbit first ran for 2 hours at a speed of 24 km/h. Then, the rabbit rode a bicycle for 3 hours, and finally, the rabbit traveled on a train for 5 hours at a speed of 48 km/h. The total distance covered by the rabbit was 357 km.

To find the speed at which the rabbit traveled on the bicycle, we can use the formula:

Speed = Distance / Time

Let's calculate the distance covered by the rabbit on each mode of transportation:

- Distance covered while running: 2 hours * 24 km/h = 48 km - Distance covered while riding a bicycle: Unknown - Distance covered while traveling on a train: 5 hours * 48 km/h = 240 km

Now, let's calculate the distance covered by the rabbit on the bicycle:

Total distance = Distance covered while running + Distance covered on the bicycle + Distance covered on the train

357 km = 48 km + Distance covered on the bicycle + 240 km

Simplifying the equation:

Distance covered on the bicycle = 357 km - 48 km - 240 km

Distance covered on the bicycle = 69 km

Therefore, the rabbit traveled a distance of 69 km on the bicycle.

To find the speed at which the rabbit traveled on the bicycle, we can use the formula:

Speed = Distance / Time

The time spent on the bicycle is given as 3 hours.

Speed on the bicycle = Distance covered on the bicycle / Time spent on the bicycle

Speed on the bicycle = 69 km / 3 hours

Speed on the bicycle = 23 km/h

Therefore, the rabbit traveled on the bicycle at a speed of 23 km/h.
