Question

((((3мин х 25км/ч) х 1200м) : 450000см) : 3м/с) х 540м/мин Помогите пожалуйста решить. Заранее спасибо.

Answer 1

((((3мин * 25км/ч) * 1200м) : 450000см) : 3м/с) * 540м/мин = 999 м
1) 3 мин * 25 км/ч = 0,05 ч * 25 км/ч = 1,25 км
2) 1,25 км * 1200 м = 1250 м * 1200 м = 1500000 м 
3) 1500000 м : 450000 см =  1500000 м : 4500 м = 333,33 м 
4) 333,33 м : 3 м/с = 111,11 с
5) 111,11 с * 540 м/мин = 1,85 мин * 540 м/мин = 999 м

Answer 2

Calculating the Expression Step by Step:

To solve the given expression, let's break it down step by step.

1. Convert 3 minutes to hours: - 3 minutes = 3/60 hours - 3 minutes = 0.05 hours

2. Calculate the distance traveled at 25 km/h in 0.05 hours: - Distance = Speed × Time - Distance = 25 km/h × 0.05 h - Distance = 1.25 km

3. Convert 1200 meters to kilometers: - 1200 meters = 1200/1000 kilometers - 1200 meters = 1.2 kilometers

4. Convert 450000 centimeters to meters: - 450000 centimeters = 450000/100 meters - 450000 centimeters = 4500 meters

5. Convert 3 meters/second to kilometers/minute: - 3 meters/second = 3 × 60 meters/minute - 3 meters/second = 180 meters/minute

6. Calculate the total distance traveled: - Total distance = (1.25 km + 1.2 km + 4500 m) = (1.25 km + 1.2 km + 4.5 km) = 6.95 km

7. Calculate the speed in meters/minute: - Speed = 540 m/minute

8. Calculate the time taken to travel 6.95 km at a speed of 540 m/minute: - Time = Distance / Speed - Time = 6950 meters / 540 meters/minute - Time ≈ 12.87 minutes

Final Answer:

The expression results in approximately 12.87 minutes.
