1. A man cruises his new model Ferrari north 8 mi. and then turns east at 12 mi/hr. At whatrate was his distance from the starting point changing 3 hrs after he left the point.2. An observers watches a plane approach at a speed of 600 mi/hr and at an altitude of 4miles. At what rate is the angle of elevation of the observer's line of sight changing whenthe horizontal distance between plane and observer is 5 miles.3. An architect is asked to design a game room in the shape of an isosceles trapezoid,where the non parallel sides and the shorter of the parallel side measure 20 ft. How long

given speed v = 12 mi/h time t = 3 hr hence distance travelled in east direction x=v*t=12*3 =36 mi
