Question

За 8 минут самолет ,двигаясь с одинаковой скоростью ,пролетел 96 км. Какое расстояние он пролетел за 40 минут, если его средняя скорость увеличилась на 2 км/мин

Answer 1

1)96 : 8 = 12(км/мин) - средняя скорость самолёта
2) 12 + 2 = 14(км/мин) - увеличенная скорость самолёта
3) 14 * 40 = 560(км)
Ответ: 560км пролетит самолёт с увеличенной скоростью.

Answer 2

Calculating the Distance Traveled

To calculate the distance the plane traveled in 40 minutes with an increased average speed, we can use the formula:

Distance = Speed × Time

Given that the plane traveled 96 km in 8 minutes with a constant speed, we can calculate its original speed using the formula:

Speed = Distance / Time

Let's calculate the original speed first and then use it to find the distance traveled in 40 minutes.

Calculating the Original Speed

Using the given information: - Distance traveled in 8 minutes = 96 km

We can calculate the original speed: ``` Speed = Distance / Time Speed = 96 km / 8 min Speed = 12 km/min ``` The original speed of the plane was 12 km/min.

Calculating the Distance Traveled in 40 Minutes with Increased Speed

Given: - Original speed = 12 km/min - Increased speed = 12 km/min + 2 km/min = 14 km/min - Time = 40 minutes

We can calculate the distance traveled with the increased speed: ``` Distance = Speed × Time Distance = 14 km/min × 40 min Distance = 560 km ``` The plane traveled a distance of 560 km in 40 minutes with the increased speed of 14 km/min.
