An airplane leaves New York at 1:10 PM and arrives in Miami, 1125 miles away, at 3:40 PM. What is its average speed in miles per hour?
Isn't the formula speed = distance/time? It didn't work for me though, I got about 700 MPH.

$450 \times 2.5 = 1125$ as a hint. Try finding miles traveled per minute and then converting minutes into hours. – 123 Jan 10 '15 at 15:33

I see my mistake. I did 1125/1.5, when it's supposed to be 2.5. A simple math error. The answer is 450.
