Question

Quizplus · Accepted Answer

Average velocity is calculated by dividing the total displacement by the total time taken.

Total displacement = (6.7 miles to the east) - (1.1 miles to the west) = 5.6 miles to the east
Total time = 5.1 hours + 1.0 hours = 6.1 hours

Average velocity = total displacement ÷ total time = 5.6 miles ÷ 6.1 hours ≈ 0.92 mph

Therefore, the answer is A) 0.92 mph.
