Question

За 3 минуты самолет пролетит 30км пути . Сколько километров пути он пролетит о за 40 минуут если будет лететь со скоростью большей на 5км. В чам.

Answer 1

1)30:3= 10 (км/мин)    первоначальная скорость самолета 
2) 10+5= 15 (км/мин)  скорость самолета, увеличенная на 5 км/мин
3) 15×40= 600 (км )
Ответ: 600 км пролетит самолет за 40 минут.

Answer 2

1)30:3=10(км/мин.) - старая скорость самолета
2)10+5=15(км/мин.) - новая скорость самолета
3)40*15=600(км.) - пролетит за 40 мин.
Ответ: 60 км

Answer 3

Calculation of Distance Traveled

To calculate the distance traveled by the plane in 40 minutes, we can use the information given that the plane travels 30 km in 3 minutes. We also know that the plane will be flying at a speed 5 km/h faster than its previous speed.

Let's break down the problem step by step:

1. Calculate the speed of the plane in km/min: - The plane travels 30 km in 3 minutes, so its speed is 30 km / 3 min = 10 km/min. 2. Calculate the new speed of the plane: - The new speed of the plane is 5 km/h faster than its previous speed. - To convert km/h to km/min, we divide by 60 (since there are 60 minutes in an hour). - So, the new speed of the plane is (10 km/min + 5 km/h / 60 min) = 10.0833 km/min. 3. Calculate the distance traveled in 40 minutes: - Multiply the new speed of the plane by the time of 40 minutes: - Distance = 10.0833 km/min * 40 min = 403.33 km.

Therefore, the plane will travel approximately 403.33 km in 40 minutes if it flies at a speed 5 km/h faster than its previous speed.
