top speed of a peregrine falcon is 240 miles per hour
240 x 1/5 = 48
48-1 = 47
sailfish can swim 47 miles per hour
Answer: The top speed that a sailfish can swim at [tex](\dfrac{x}{5}-1)\ mph[/tex]
Step-by-step explanation:
Since we have given that
Top speed of a peregrine falcon be 'x'.
One fifth the top speed of a peregrine falcon would be
[tex]\dfrac{1}{5}x[/tex]
1 mile per hour less than the above is expressed as
[tex]\dfrac{1}{5}x-1[/tex]
According to question, the top speed that a sailfish can swim would be
[tex]\dfrac{1}{5}x-1[/tex]
Hence, the top speed that a sailfish can swim at [tex](\dfrac{x}{5}-1)\ mph[/tex]
