Question

Самолёт может пролететь 4500км за 5 часов какое расстояние он пролетит за это время если уменьшит скорость на 120км ч решите пожалуйсто двумя способами

Answer 1

S=4500km
t=5 часов
v=s/t
v=4500/5=900km в час летит самолет.
уменьшаем скорость на 120 км ч
900-120 = 780км ч новая скорость свмолета
s=v.t=780.5=3900km пролетит

Answer 2

45000:5=9000
9000-120=8 880

Answer 3

Calculation 1:

To calculate the distance the plane will travel in 5 hours at a reduced speed, we need to subtract the reduced speed from the original speed and then multiply it by the time.

Given: - Original speed: 4500 km - Time: 5 hours - Reduced speed: 120 km/h

To find the distance traveled at the reduced speed, we can use the formula:

Distance = (Original speed - Reduced speed) * Time

Substituting the given values:

Distance = (4500 km - 120 km/h) * 5 hours

Calculating the result:

Distance = (4380 km) * 5 hours

Distance = 21900 km

Therefore, the plane will travel a distance of 21900 km in 5 hours at the reduced speed of 120 km/h.

Calculation 2:

Another way to calculate the distance the plane will travel in 5 hours at a reduced speed is to calculate the distance traveled at the original speed and then subtract the distance traveled at the reduced speed.

Given: - Original speed: 4500 km - Time: 5 hours - Reduced speed: 120 km/h

To find the distance traveled at the original speed, we can use the formula:

Distance = Original speed * Time

Substituting the given values:

Distance = 4500 km * 5 hours

Calculating the result:

Distance = 22500 km

Next, we need to calculate the distance traveled at the reduced speed. We can use the same formula:

Distance = Reduced speed * Time

Substituting the given values:

Distance = 120 km/h * 5 hours

Calculating the result:

Distance = 600 km

Finally, we subtract the distance traveled at the reduced speed from the distance traveled at the original speed:

Distance = 22500 km - 600 km

Distance = 21900 km

Therefore, the plane will travel a distance of 21900 km in 5 hours at the reduced speed of 120 km/h.
