Question

Самолет пролетел 10 минут со скоростью. 12км/мин, затем увеличил скорость на 3км/мин и пролетел еще 10 мин. какое расстояние он пролетел за эти 20 минут?

Answer 1

Сам думай! на контрольной ты как будешь работать? так что сам думай!

Answer 2

1)12+3=15(км/мин)-увеличил
2)12+16=27(км/мин)-вместе
3)27•20=540(км)
Ответ:за эти 20 минут он пролетел 540 км

Answer 3

Calculation of Distance Traveled

To calculate the distance traveled by the plane, we need to determine the total distance covered during the two intervals of 10 minutes each.

Let's break down the problem step by step:

1. In the first 10 minutes, the plane traveled at a speed of 12 km/min. 2. In the next 10 minutes, the plane increased its speed by 3 km/min, resulting in a new speed of 15 km/min.

To find the distance traveled during each interval, we can use the formula:

Distance = Speed × Time

For the first interval: - Speed = 12 km/min - Time = 10 min

Using the formula, we can calculate the distance traveled during the first interval:

Distance1 = 12 km/min × 10 min = 120 km For the second interval: - Speed = 15 km/min - Time = 10 min

Using the formula, we can calculate the distance traveled during the second interval:

Distance2 = 15 km/min × 10 min = 150 km To find the total distance traveled, we add the distances from both intervals:

Total Distance = Distance1 + Distance2 = 120 km + 150 km = 270 km

Therefore, the plane traveled a total distance of 270 km during the 20-minute period.
