Question

4) а) Самолет пролетел 391,5км за 2,7 часа: Сколько километров он пролетит за 4,2 часа, если будет лететь с такой же скоростью?

Answer 1

Ответ:

609км

Пошаговое объяснение:

391,5км - 2,7ч

хкм - 4,2ч

х=391,5*4,2:2,7=609км

Answer 2

Ответ:
609
Пошаговое объяснение:
391,5:2,7=149(скорость)
149*4,2=609(растоян.)

Answer 3

Calculation of Distance Traveled

To calculate the distance traveled by the plane, we can use the formula:

Distance = Speed × Time

Given that the plane traveled 391.5 km in 2.7 hours, we can calculate its speed using the formula:

Speed = Distance / Time

Let's calculate the speed first:

Speed = 391.5 km / 2.7 hours = 145 km/h Now, we can use the speed to calculate the distance the plane will travel in 4.2 hours:

Distance = Speed × Time

Distance = 145 km/h × 4.2 hours = 609 km

Therefore, if the plane continues to fly at the same speed, it will travel approximately 609 kilometers in 4.2 hours.
