Practice Question
Laura walks every evening on the edges of a sports field near her house. The field is in the shape of a rectangle 300 feet (ft) long and 200 ft wide, so 1 lap on the edges of the field is 1,000 ft. She enters through a gate at point G, located exactly halfway along the length of the field.
Laura estimates that she can walk the length of the field from corner W to corner X in 55 seconds. To the nearest tenth of a mile per hour, what is her walking speed? (1 mile = 5,280 feet)

Answer Choices
- A: 3.7
- B: 5.5
- C: 3.4
- D: 5.3
Correct Answer: B
Rationale: Length = 300 ft, time = 55 sec. Speed = 300 / 55 ? 5.4545 ft/sec. Convert: (5.4545 * 3600) / 5280 ? 5.5 mph. Thus, the correct answer is 5.5.
