Question

За 8 минут самолёт пролетел 96 км с одинаковой скоростью, какое расстояние он пролетит за 40 минут если его скорость увеличится на 2 км

Answer 1

96/8=12 км/ч была скорость самолета
12+2=14 км/ч стала скорость самолета
40*14=560 км

Answer 2

96:8 =12скорость
12+2=14новая скорость
14*40=560

Answer 3

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 speed increases by 2 km.

Solution

To find the distance the plane will travel in 40 minutes, we can use the formula:

Distance = Speed × Time

Let's calculate the distance using this formula.

Calculation

Given: - Initial distance = 96 km - Initial time = 8 minutes - Speed increase = 2 km - Target time = 40 minutes

To find the new speed, we need to add the speed increase to the initial speed. Since speed is distance divided by time, we can calculate the initial speed using the given information:

Initial speed = Initial distance / Initial time

Initial speed = 96 km / 8 minutes

Initial speed = 12 km/minute

Now, we can calculate the new speed:

New speed = Initial speed + Speed increase

New speed = 12 km/minute + 2 km/minute

New speed = 14 km/minute

Finally, we can calculate the distance the plane will travel in 40 minutes using the new speed:

Distance = New speed × Target time

Distance = 14 km/minute × 40 minutes

Distance = 560 km

Answer

The plane will travel a distance of 560 km in 40 minutes if its speed increases by 2 km.
