At the start of a trip, the odometer on a car read 21,395. at the end of the trip, 13.5 hours later, the odometer read 22,125. assume the scale on the odometer is in miles. what is the average speed the car traveled during this trip?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
