An air traffic controller is tracking two planes. To start, Plane A was at an altitude of 990 meters, and Plane B was at an altitude of 1476 meters. Plane A is losing altitude at 18 meters per second, and Plane B is losing altitude at 27 meters per second.Let x be the number of seconds that have passed.(a)For each plane, write an expression for the altitude of the plane after x seconds.AltitudeofPlaneA(in=meters)AltitudeofPlaneB(in=meters)(b)Write an equation to show when the two planes would be at the same altitude.

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 2093 feet and Plane B is just taking off. Plane A is gaining altitude at 30.25 feet per second and Plane B is gaining altitude at 75.75 feet per second.How many seconds will pass before the planes are at the same altitude?secondsWhat will their altitude be when they're at the same altitude?feet

An air traffic controller spots two planes at the same altitude converging on a point as they fly at right angles to each other. One plane is 150 miles from the point moving at 300 miles per hour. The other plane is 200 miles from the point moving at 400 miles per hour.(a)At what rate (in mi/hr) is the distance s between the planes changing?

An aircraft has been instructed to climb from its present altitude of 8,000 ft to its cruising altitude of 29,000 ft.  The plane ascends at a rate of 3,000 ft/min.  How long (in min) does it take for the plane to change altitude?  Write only the numerical value to the nearest minute, you may omit the units of min.

Two airplanes leave an airport at the same time and travel in opposite directions. One plane travels 78 kmh faster than the other. If the two planes are 6400 kilometers apart after 4 hours, what is the rate of each plane?Note that the ALEKS graphing calculator can be used to make computations easier.Rate of the faster plane: kmhRate of the slower plane: kmh

Learning goal 3: A plane travels at +370 km/h for 6 hours, and then at –470 km/h for 5 hours.Determine which of the following are true. Note: You'll need a calculator or a pen and paper to answer.The plane finished 100 km away from where it startedThe plane passed over its starting position later in its journeyThe plane travelled a total distance of 4570 kmThe plane finished 4570 km away from where it started
