Question

За 8 мин самолет, двигаясь с одинаковой скоростью, пролетел 96 км. Какое расстояние он пролетит за 40 мин, если его средняя скорость увеличится на 2 км/мин?Хелп ми плиз!!!

Answer 1

За восемь минут самолёт пролетел 96 км. Следовательно, его средняя скорость: 96/8=12 км/мин 
Если она увеличится на 2 км в минуту, то составит: 14 км/мин 
За 40 минут с такой скоростью он пролетит: 14*40=560 км.

Answer 2

Problem Analysis

We are given that a plane traveled 96 km in 8 minutes at a constant speed. We need to find the distance it will travel in 40 minutes if its average speed increases by 2 km/min.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's calculate the initial speed of the plane using the given information. We know that the plane traveled 96 km in 8 minutes. Therefore, the initial speed can be calculated as follows:

Initial Speed = Distance / Time = 96 km / 8 min = 12 km/min

Now, we need to find the distance the plane will travel in 40 minutes when its speed increases by 2 km/min. Let's calculate the new speed:

New Speed = Initial Speed + Increase in Speed = 12 km/min + 2 km/min = 14 km/min

Using the formula distance = speed × time, we can calculate the distance the plane will travel in 40 minutes:

Distance = New Speed × Time = 14 km/min × 40 min = 560 km

Therefore, the plane will travel a distance of 560 km in 40 minutes when its average speed increases by 2 km/min.

Answer

The plane will travel a distance of 560 km in 40 minutes when its average speed increases by 2 km/min.
