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. The rabbit first ran for 2 hours at a speed of 24 km/h, then cycled for 3 hours, and finally traveled by train for 5 hours at a speed of 48 km/h. The total distance covered by the rabbit was 357 km.

Let's calculate the distance covered during each phase of the journey:

1. Running: The rabbit ran for 2 hours at a speed of 24 km/h. Therefore, the distance covered during this phase is:

Distance = Speed × Time = 24 km/h × 2 h = 48 km

2. Cycling: The rabbit cycled for 3 hours. However, we don't know the speed at which it was cycling. Let's assume the speed on the bicycle is x km/h. Therefore, the distance covered during this phase is:

Distance = Speed × Time = x km/h × 3 h = 3x km

3. Train: The rabbit traveled by train for 5 hours at a speed of 48 km/h. Therefore, the distance covered during this phase is:

Distance = Speed × Time = 48 km/h × 5 h = 240 km

Now, let's sum up the distances covered during each phase to find the total distance:

Total Distance = Running Distance + Cycling Distance + Train Distance

357 km = 48 km + 3x km + 240 km

To find the speed at which the rabbit was cycling, we can rearrange the equation:

3x km = 357 km - 48 km - 240 km

3x km = 69 km

x km = 69 km / 3

x km ≈ 23 km/h

Therefore, the rabbit was cycling at a speed of approximately 23 km/h.
