Question

За полтора часа самолёт прошёл 810 км. Какое расстояние он пролетит за 22 часа? Если скорость не изменится.

Answer 1

Дано:                                                  Решение:
S = 810 км
t = 1,5 ч                      S = vt   =>  v = S/t = 810 : 1,5 = 540 (км/ч)
t₁ = 22 ч                      S₁ = vt₁ = 540 * 22 = 11880 (км)
v = const.
------------------
Найти: S₁ - ?

Ответ: 11880 км.

Решение через пропорцию:

      v = const.  =>    S/t = S₁/t₁  
                                 S₁ = St₁/t = 810*22:1,5 = 11880 (км)

Ответ: 11880 км.                    

Answer 2

Calculation of Distance Traveled

To calculate the distance the plane will travel in 22 hours, we can use the information given: the plane traveled 810 km in 1.5 hours.

To find the distance traveled in 22 hours, we can set up a proportion:

Distance traveled in 1.5 hours / Time taken in 1.5 hours = Distance traveled in 22 hours / Time taken in 22 hours

Let's solve this proportion:

810 km / 1.5 hours = x km / 22 hours

To find x, we can cross-multiply and solve for x:

810 km * 22 hours = 1.5 hours * x km

17820 km = 1.5x km

Dividing both sides by 1.5:

17820 km / 1.5 = x km

The plane will travel 11,880 km in 22 hours if its speed remains constant.
