Question

1 за 7 часов Самолет пролетел на 1260 км больше чем за 4 часа какое расстояние самолет пролетит за 4 часа если его скорость не изменилась 2 89×а-4084=37183Пж срачняфка

Answer 1

1. V = 1260:(7-4) = 1260:3 = 420 км/ч - скорость самолета
2. 420*4= 1680 км - пролетел самолет за 4 часа
Ответ: 1680 км

Answer 2

1. Let's use the formula distance = rate x time, where rate is the speed of the plane and time is the duration of the flight.

If the plane traveled 1260 km more in 7 hours than in 4 hours, then we can set up the following equation:

distance with 7 hours = distance with 4 hours + 1260 km

rate x 7 = rate x 4 + 1260

Simplifying this equation, we get:

rate = 180 km/h

Now that we know the rate, we can use the formula distance = rate x time to find the distance traveled in 4 hours:

distance = rate x time

distance = 180 km/h x 4 h

distance = 720 km

Therefore, the plane would travel 720 km in 4 hours at a constant speed of 180 km/h.

2. To solve the equation 89×а-4084=37183 for а, we can isolate а on one side of the equation by adding 4084 to both sides and then dividing by 89:

89×а-4084=37183

89×а=41267

а=41267/89

а≈463.5

Therefore, the solution to the equation is а≈463.5.
