Question

Ученики отправились на экскурсию и ехали 1 час на автобусе и 1 час на поезде, их путь составил 90 км, определи скорость автобуса и скорость поезда, если средняя скорость поезда в 2 раза больше средней скорости автобуса

Answer 1

Х - скорость автобуса 
2х- скорость поезда 
х+2х=90
3х=90
х=90/3
х=30 - скорость автобуса 
30*2 = 60 - скорость поезда

Answer 2

Calculating the Speeds of the Bus and Train

To determine the speed of the bus and the speed of the train, we can use the formula:

Speed = Distance / Time

Given that the students traveled 90 km, spending 1 hour on the bus and 1 hour on the train, we can calculate the speeds of the bus and the train using the information provided.

Calculating the Speed of the Bus

The speed of the bus can be calculated using the formula: Speed of Bus = Distance / Time

Substituting the given values: Speed of Bus = 90 km / 1 hour = 90 km/h

Calculating the Speed of the Train

The speed of the train is given to be twice the speed of the bus. Therefore: Speed of Train = 2 * Speed of Bus = 2 * 90 km/h = 180 km/h So, the speed of the bus is 90 km/h and the speed of the train is 180 km/h.

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
