Answer:
In 1 min a gazelle runs 3,900 ft.
As a fraction, 1/65
In order to find the solution to this problem you could use a table.
Since we are using seconds we have to convert the 1 min = 60 seconds.
Sec | 12 | 60
Fts | 780 | x
12 goes into 60 5 times, so we have to multiply 780 by 5 which gives us 3900.
x=3900
