A pilot can travel 468 miles with the wind in the same amount of time as...
90) A boat can travel 9 mi downstream in the same amount of time it can travel 6 mi upstream. If the speed of the boat in still water is 10 mph, find the speed of the current. 91) When the wind is blowing at 40 mph, a plane flying at a constant speed can travel 800 mi with the wind in the same amount of time it can fly 600 mi against the wind. Find the speed of the...
8) A certain aircraft can fly 1260 miles with the wind in 5 hours and travel the same distance against the wind in 7 hours. What is the speed of the wind?
An airplane pilot wishes to fly due west. A wind of 72.0 km/hkm/h is blowing toward the south. Part A If the airspeed of the plane (its speed in still air) is 335.0 km/hkm/h, in which direction should the pilot head? Express your answer in degrees. Part B What is the speed of the plane over the ground? Express your answer in kilometers per hour.
The wind velocity v, is 40 miles per hour from east to west while an air speed v, of 100 miles per hour due north airplane travels with (a) Find the speed of the airplane relative to the ground, vi + v2. (b) If the plane starts at (1,3), what is it's position after 90 minutes? The wind velocity v, is 40 miles per hour from east to west while an air speed v, of 100 miles per hour due...
The average annual wind speed in Rochester, Minnesota is 15.5 miles per hour. If a sample of 95 days are used to determine the average wind speed, find the 98% confidence interval of the mean. Assume the standard deviation was 3.2 miles per hour. (Show Work)
A wind is blowing with a speed of 30 miles per hour in a direction of N45 degrees E. Find the components of the vector representing the velocity of the wind.
an airplane pilot wishes to fly due south. A wind of 25 km/h is blowing toward the west. If the flying speed of the plane is 300.0 km/h (its speed in still air), in what direction should the pilot head? answer is 85 degrees South of East using inverse cosine, but I'm not sure how it was done. I'm having a hard time making a diagram/visualizing so please include diagrams and your reasoning behind the answer.
An ultralight airplane can travel 28.0 m/s in still air. The wind is blowing from north to south at 12.0 m/s. If you wish to travel due east, what direction should you head in order to compensate for the wind?
An energy company wants to choose between two regions in a state to install energy-producing wind turbines. A researcher claims that the wind speed in Region A is less than the wind speed in Region B. To test the regions, the average wind speed is calculated for ninety days in each region. The mean wind speed in Region A is 13.913.9 miles per hour. Assume the population standard deviation is 2.9 miles per hour. The mean wind speed in Region...
The speed of a vehicle is inversely proportional to the time it takes to travel a fixed distance. If a vehicle travels a fixed distance at 60 miles per hour in 20 minutes, how fast must it travel to cover the same distance in 10 minutes? A. 120 mph 1 OB. 30 mph OC. 30 mph 10 OD mph
