Question

Патрульный милицейский вертолёт во время наблюдения за движением транспорта летел вдоль шоссе 16 мин,а затем увеличил скорость и летел ещё 34 мин в том же направлении.Какой длины участок шоссе облетел за то время вертолёт,если его скорость вначале была 1200 м/мин,а затем 1500 м/мин? Помогите решить задачу,пожалуйста. Дам 25 баллов

Answer 1

1200*16+1500*34=19200+51000=70200м=70,2км

Answer 2

Problem Analysis

We are given the following information: - A patrol police helicopter flew along a highway for 16 minutes at a speed of 1200 m/min. - Then, the helicopter increased its speed and flew for an additional 34 minutes in the same direction at a speed of 1500 m/min.

We need to find the length of the highway that the helicopter covered during this time.

Solution

To find the length of the highway covered by the helicopter, we can calculate the total distance traveled during the given time.

Let's calculate the distance covered during the first 16 minutes at a speed of 1200 m/min: Distance1 = Speed1 * Time1

Next, let's calculate the distance covered during the next 34 minutes at a speed of 1500 m/min: Distance2 = Speed2 * Time2

Finally, we can find the total distance covered by adding Distance1 and Distance2: Total Distance = Distance1 + Distance2

Let's substitute the given values and calculate the total distance covered by the helicopter.

Calculation

Given: - Speed1 = 1200 m/min - Time1 = 16 minutes - Speed2 = 1500 m/min - Time2 = 34 minutes

Using the formulas mentioned above, we can calculate the total distance covered by the helicopter.

Distance1 = Speed1 * Time1 = 1200 m/min * 16 min = 19200 meters

Distance2 = Speed2 * Time2 = 1500 m/min * 34 min = 51000 meters

Total Distance = Distance1 + Distance2 = 19200 meters + 51000 meters = 70200 meters

Therefore, the helicopter covered a distance of 70200 meters (or 70.2 kilometers) during the given time.

Answer

The length of the highway covered by the patrol police helicopter during the given time is 70.2 kilometers.
