Praxis 5003 Practice Question
Leslie skydived out of an airplane with a parachute. After she opened the parachute, Leslie descended at a constant rate. During the first 34 seconds after she opened the parachute, she descended 714 feet. It took 1 minute and 25 seconds for Leslie to reach the ground after she opened the parachute. How far did Leslie descend to reach the ground after she opened the parachute?
Correct Answer: C
Rationale: To determine how far Leslie descended after opening her parachute, we first convert the total descent time into seconds. 1 minute and 25 seconds equals 85 seconds. Given that Leslie descended 714 feet in the first 34 seconds, we can find her descent rate: 714 feet / 34 seconds = 21 feet per second. Over the full 85 seconds, she would descend 21 feet/second × 85 seconds = 1,785 feet.
Option A (1,270 feet) underestimates her descent. Option B (1,515 feet) also falls short of the calculated distance. Option D (2,615 feet) exceeds the total distance based on the descent rate. Thus, 1,785 feet accurately reflects her total descent.
