Question

Как решить задачу самолет летел до посадки 4 ч и пролетел 2520км. После этого он пролетел к месту назначения еще 2700 км за 5 ч . узнай среднюю скорость самолета за время всего полета

Answer 1

U ср = S общий / t общее
S общий = 2520 км + 2700 км = 5220 км
t общее = 4 ч + 5 ч = 9 ч
U ср = 5220 км / 9 ч = 580 км/ч
Ответ: U ср = 580 км/ч

Answer 2

Calculating the Average Speed of the Plane

To calculate the average speed of the plane for the entire flight, we can use the formula:

Average Speed = Total Distance / Total Time

First, we need to find the total distance traveled and the total time taken for the entire flight.

Finding the Total Distance Traveled

The plane first flew for 4 hours and covered a distance of 2520 km. After that, it flew for an additional 5 hours and covered 2700 km.

The total distance traveled by the plane is the sum of these two distances: **Total Distance =
