Answer:
Length of the bike trail is 80 miles.
Step-by-step explanation:
Jo posted a sign at the start of bike trail and every sign was at a distance of [tex]\frac{1}{4}[/tex] miles or 0.25 miles.
Let the number of signs he posted = n
Total length of the trail in the terms of n will be = 0.25n
He posted 20 signs and the 20th sign was at the end of the trail.
So the equation that represents the length of the trail will be,
0.25n = 20
[tex]\frac{0.25n}{0.25}=\frac{20}{0.25}[/tex]
n = 80 miles
Therefore, length of the bike trail is 80 miles.
