Question

An airplane leaves Orlando, FL and travels 540 miles to Washington D.C. The flight takes 90 minutes. What is the speed of the plane?

Answer 1

Answer:

Speed of the plane is 6 miles/min

Explanation:

Given:

Distance from Orlando to Washington DC = 540 miles

Time taken for travel = 90 minutes

To determine:

The speed of the plane

Explanation:

Speed is expressed as the ratio of distance traveled by the time taken

$Speed = \frac{distance}{time} \\\\Speed\ of\ the\ plane = \frac{540\ miles}{90\ min} = 6 miles/min$

Answer 2

Speed is measured in miles per hour. You have miles, so convert minutes to hours.

90 minutes x 1 hour / 60 minutes = 1.5 hours

540 miles/ 1.5 hours = 360 miles / hour
