Hey there! I'm happy to help!
The distance is equal to the speed multiplied by the time. We already have the distance and the speed, so we divide them to get the time.
240/45=5 1/3 hours
However, we want this in minutes. There are 60 minutes in one hour, so we just multiply by 60!
5 1/3×60=320
Therefore, it takes 320 minutes to drive from Orlando to Miami.
Have a wonderful day! :D
