Question

Пассажир ехал 10 часов поездом со скоростью u км в час,и летел 8 часов на самолёте со скоростью p км в час.Сколько всего км пассажир ехал на поезде и летел на самолёте? составьте предложение и найдите его значение при S=40, P=320

Answer 1

S=10v+8p
вставляем значения v и p
10*40+8*320=400+2560=2960

найдите его значение при S=40, тут не S а V
S нам нужно найти

Answer 2

Problem Analysis

The passenger traveled for 10 hours by train at a speed of u km/h and for 8 hours by plane at a speed of p km/h. We need to find the total distance traveled by the passenger on the train and the plane.

Solution

To find the total distance traveled, we can use the formula: Distance = Speed × Time

Let's calculate the distance traveled by the passenger on the train and the plane.

Distance Traveled by Train

The distance traveled by the passenger on the train can be calculated using the formula: Distance_train = Speed_train × Time_train

Given: - Time_train = 10 hours - Speed_train = u km/h

Using the formula, we can calculate the distance traveled by the passenger on the train.

Distance Traveled by Plane

The distance traveled by the passenger on the plane can be calculated using the formula: Distance_plane = Speed_plane × Time_plane

Given: - Time_plane = 8 hours - Speed_plane = p km/h

Using the formula, we can calculate the distance traveled by the passenger on the plane.

Total Distance Traveled

The total distance traveled by the passenger is the sum of the distances traveled by train and plane: Total_distance = Distance_train + Distance_plane

Let's calculate the total distance traveled by the passenger.

Calculation

Given: - Time_train = 10 hours - Speed_train = u km/h - Time_plane = 8 hours - Speed_plane = p km/h

Using the given values, we can calculate the total distance traveled by the passenger.

Result

The total distance traveled by the passenger on the train and the plane is 45u + 8p kilometers.

Substitution

Given: - u = 40 km/h - p = 320 km/h

Substituting the given values into the expression for the total distance: Total_distance = 45u + 8p Total_distance = 45(40) + 8(320) Total_distance = 1800 + 2560 Total_distance = 4360 km

Conclusion

The passenger traveled a total distance of 4360 kilometers on the train and the plane.
