karl rode his bicycle 3/8 of the distance from Lakeview to bay cove,which is 24.1 miles. how many more does he need to ride to complete his trip ?

Answer:
Karl needs to ride 15.0625 miles more to complete his trip.
Step-by-step explanation:
There is a sketch attached to this answer.
If we divide the distance into eight equal parts, we can see graphically that Karl still needs to ride [tex]\frac{5}{8}[/tex] of the distance.
In other words, we are dealing here with fractions. The total is 24.1mi (in terms of fractions the total is 1).
We can confirm this following the next steps:
Then, Karl still needs to ride 15.0625 miles more to complete his trip.
We can check this result:
[tex]\\ \frac{3}{8}+\frac{5}{8}=\frac{3+5}{8}=\frac{8}{8}=1.[/tex]
[tex]\\ \frac{3}{8}*(24.1mi)=9.0375mi[/tex]
[tex]\\ \frac{5}{8}*(24.1mi)=15.0625mi[/tex]
Which give us the total distance = 9.0375mi + 15.0625mi = 24.1mi.
