Charles Lindbergh made the first solo airplane flight from New York to paris.
His flight covered about 3 610 miles in 33.5 hours.
Let’s find the Unit Rate for this given data:
=> 3 610 miles is the total distance
=> 33.5 hours is the time
Let’s divide the distance by time to get the answer
=> 3 610 / 33.5
=> 107.8 miles per hour – this is the unit rate that Charles travelled in plane from New York to Paris
