Question

Самолет за время 40 секунд пролетел расстояние 12 км. Какова его скорость м/с?

Answer 1

1) 12000 : 40 = 300 (м/с)
Ответ: скорость самолета 300 метров с секунду.
S = 12000 м.
t = 40 сек.
v = S:t

Answer 2

12 км/40 с = 12 × 1000 м/40 с = 12000м/40с = 1200м/4с = 300м/с.

Answer 3

Calculation of Speed

To calculate the speed of the plane, we can use the formula:

Speed = Distance / Time

Given that the plane traveled a distance of 12 km in 40 seconds, we can substitute these values into the formula to find the speed:

Speed = 12 km / 40 seconds

To convert the speed to meters per second, we need to convert the distance from kilometers to meters:

Speed = 12,000 meters / 40 seconds

Now we can calculate the speed:

Speed = 300 meters per second

Therefore, the speed of the plane is 300 m/s.
