Question

A chair left at a ski resort is 4806 feet long and takes 9 minutes. What is the average speed of the lift in miles per hour?

Answer 1

The average speed of the lift is approximately 6.07 miles per hour.

What is the average speed of the lift in miles per hour?

Average speed is expressed mathematically as;

Average Speed = Distance / Time

Given the data in the question;

• Distance = 4806ft = ( 4806/5280)miles = 801/880 miles
• Time = 9min = ( 9/60 )hr = 3/20 hr
• Average speed = ?

Plug in the values into the above equation.

Average Speed = Distance / Time

Average Speed = 801/880 miles ÷ 3/20 hr

Average Speed = 801/880 × 20/3

Average Speed = 267/44 mi/hr

Average Speed = 6.07 mi/hr

Therefore, the average speed of the lift is approximately 6.07 miles per hour.
