Question

Самолёт пролетел 2500 км за 3 ч.В первый час он пролетел 2/ всего пути,а во второй 30 % всего пути.Какое расстояние пролетел самолёт за третий час?

Answer 1

2500/2=1250 за 1 час
2500/100*30=750 за 2 час
2500-1250+750=500 км за 3 час

Answer 2

Calculation of the Distance Traveled by the Plane

To calculate the distance traveled by the plane in the third hour, we need to understand the information provided.

According to the given information: - The plane flew a total distance of 2500 km in 3 hours. - In the first hour, the plane flew 2/5 (or 40%) of the total distance. - In the second hour, the plane flew 30% of the total distance.

To find the distance traveled in the third hour, we need to determine the remaining percentage of the total distance that the plane covered in the first two hours.

Let's calculate the distances traveled in the first two hours:

- Distance traveled in the first hour: 2/5 of 2500 km = 1000 km. - Distance traveled in the second hour: 30% of 2500 km = 750 km.

To find the remaining distance, we subtract the sum of the distances traveled in the first two hours from the total distance:

Remaining distance = Total distance - (Distance traveled in the first hour + Distance traveled in the second hour)

Remaining distance = 2500 km - (1000 km + 750 km) = 2500 km - 1750 km = 750 km

Therefore, the plane traveled 750 km in the third hour.

Answer:

The plane traveled a distance of 750 km in the third hour.
