Answer: The person bike 20 miles in an hour.
Step-by-step explanation:
Given: At a constant speed, a person travels [tex]2\dfrac12[/tex] miles in [tex]\dfrac18[/tex] hour.
As [tex]2\dfrac12=\dfrac{2\times2+1}{2}=\dfrac{5}{2}[/tex]
So, in [tex]\dfrac18[/tex] hour, distance traveled = [tex]\dfrac52[/tex] miles
As time and distance are proportional, Multiply 8 om both sides , we get
In 1 hour, distance traveled = [tex]\dfrac52\times8[/tex] miles
[tex]=5\times4[/tex] miles= 20 miles
Hence, the person bike 20 miles in an hour.
