Praxis 5511 Practice Test Practice Question
Yoko is planning a trip from New York to Tokyo. She will travel on a commercial airliner that flies at an average speed of 529 miles per hour. If the distance from New York to Tokyo is 6,735 miles, which of the following is the best estimate of the time, in hours, of her trip?
Correct Answer: B
Rationale: To estimate the travel time, divide the total distance by the average speed. The calculation is 6,735 miles ÷ 529 miles per hour, which approximates to about 12.7 hours.
Option A (11 hours) underestimates the time, as it does not account for the full distance traveled. Option C (15 hours) slightly overestimates but is closer than A. Option D (17 hours) greatly exceeds the time calculated, making it an unrealistic choice. Therefore, 13 hours (Option B) is the best estimate, as it closely aligns with the calculated time while remaining practical for a long-distance flight.
