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

Answer 1

1)24*2=48(км)-заяц пробежал.
2)48*5=240(км)-он проехал на поезде.
3)240+48=288(км)-он пробежал и проехал на поезде вместе.
4)357-288=69(км)-заяц проехал на велосипеде.
5)69:3=23(км/ч)
Ответ:23 км/ч ехал заяц на велосипеде.

Answer 2

Calculation of the Rabbit's Speed on a Bicycle

To calculate the speed at which the rabbit was riding the bicycle, we need to determine the distance covered by the rabbit on foot and by train, and then subtract that from the total distance traveled.

The rabbit ran for 2 hours at a speed of 24 km/h, covering a distance of 2 * 24 = 48 km. The rabbit then rode the bicycle for 3 hours, but we don't have the speed of the bicycle. Therefore, we cannot calculate the distance covered by the rabbit on the bicycle. Finally, the rabbit traveled by train for 5 hours at a speed of 48 km/h, covering a distance of 5 * 48 = 240 km.

To find the speed at which the rabbit was riding the bicycle, we need to subtract the distances covered on foot and by train from the total distance traveled.

Total distance traveled = 357 km Distance covered on foot = 48 km Distance covered by train = 240 km

To find the distance covered on the bicycle, we subtract the sum of the distances covered on foot and by train from the total distance traveled:

Distance covered on bicycle = Total distance traveled - (Distance covered on foot + Distance covered by train) Distance covered on bicycle = 357 km - (48 km + 240 km) Distance covered on bicycle = 357 km - 288 km Distance covered on bicycle = 69 km

Now, we can calculate the speed at which the rabbit was riding the bicycle by dividing the distance covered on the bicycle by the time spent riding the bicycle:

Speed on bicycle = Distance covered on bicycle / Time spent riding the bicycle Speed on bicycle = 69 km / 3 hours Speed on bicycle = 23 km/h

Therefore, the rabbit was riding the bicycle at a speed of 23 km/h.

Please note that the speed of the bicycle was not provided in the question, so we had to calculate it based on the given information.
