Afalcon flew 70 miles in 3 hours. what was the speed of the falcon? speed = distance/time ; 1 mile = 1609 meters.
a. 10.4 meters per second
b. 23.3 meters per second
c. 52.2 meters per second
d. 93.9 meters per second

70 miles in 3 hours = 70/3 ≈ 23.33 mph

If 1 mile = 1609 m  the 23.33 miles≈ 37543.33 meter per hour.
Divide by 60 to change to meters per minute and again by 60 to change meters per minute to meters per second - Shortcut is to divide by 60 x 60 or 3600
37543.33  ≈ 10.428 meters per second.  Answer a. is correct
3600

The first option would be correct if it were one half and not one
