Answer:
T = 2.5 + M is the equation to determine where Tamara is in the race , where T denotes distance covered by Tamara and M denotes covered by Marcia.
Total length of race is 8.67 kilometers and Tamara is at 6.5 kilometers in the race.
Step-by-step explanation:
Given : Marsha and Tamara are running a race. Marcia has run 4 kilometers. Tamara has completed [tex]\frac{3}{4}[/tex] of the race and is 2.5 kilometers ahead of Marcia.
We have to find where Tamara is in the race.
Let k represent the total length of the race in kilometers.
Marcia has run 4 kilometers.
ans Tamara is 2.5 kilometers ahead of Marcia.
Let T denotes distance covered by Tamara and M denotes covered by Marcia.
Mathematically written as,
T = 2.5 + M = 2.5 + 4 = 6.5 Kilometers.
Also , given,
Tamara has completed [tex]\frac{3}{4}[/tex] of the race.
that is [tex]\frac{3}{4}\times k=6.5[/tex]
Solve for k , we get,
[tex]\frac{3}{4} k=6.5\times \frac{4}{3}=8.67[/tex] kilometers.
Thus, total length of race is 8.67 kilometers and Tamara is at 6.5 kilometers in the race.
