Question

Турист проехал на поезде и на теплоходе 605 км.Средняя скорость поезда 60 км/с, а теплохода 25 кс/ч.Сколько времени туристы ехали на поезде и сколько - на теплоходе, если известно, что на теплоходе он ехал на 3 часа меньше чем на поезде?

Answer 1

Х час на теплоходе  
(х + 3) час на поезде  
60*(х + 3) км - проехал на поезде 
25 * х км - расстояние на теплоходе 
Уравнение 
60*(х + 3) + 25х = 605 
60х + 25х = 605 - 180 
85х = 425
х = 425 : 85  
х = 5 часов на теплоходе  
5 + 3 = 8 часов на поезде

Answer 2

Problem Analysis

A tourist traveled a total distance of 605 km by train and boat. The average speed of the train was 60 km/h, and the average speed of the boat was 25 km/h. The tourist spent 3 hours less on the boat than on the train. We need to calculate the time spent on the train and the time spent on the boat.

Calculation

Let's denote the time spent on the train as t and the time spent on the boat as t - 3 (since the tourist spent 3 hours less on the boat than on the train).

The distance traveled by the train is given by the formula: distance = speed * time. Therefore, the distance traveled by the train is 60t km.

Similarly, the distance traveled by the boat is 25(t - 3) km.

Since the total distance traveled is 605 km, we can write the equation: 60t + 25(t - 3) = 605.

Now, let's solve this equation to find the values of t and t - 3.

Solution

Expanding the equation: 60t + 25t - 75 = 605.

Combining like terms: 85t - 75 = 605.

Adding 75 to both sides: 85t = 680.

Dividing both sides by 85: t = 8.

Therefore, the time spent on the train is 8 hours, and the time spent on the boat is 8 - 3 = 5 hours.

Answer

The tourist spent 8 hours on the train and 5 hours on the boat.
