Answer:
I believe the answer is 80 meters.
Note: I am not sure how to explain this so that it makes sense.
Answer:
-20/49
Step-by-step explanation:
Inferring that they are the only three players, all of their votes equal to 100%. If Dev gets 10%, that leaves 90% for Joe & Holly. You are now looking for a number that , when doubled adds to 90%.
Using an equation: a+2a=90
Solve for a.
3a=90 a=90/3
Now we have 10%,30%, & 60%
first speed --- x mph
return speed -- x+16 mph
6/x + 6/(x+16) = 1
times each term by x(x+16)
6(x+16) + 6x = x(x+16)
x^2 + 4x - 96 = 0
(x-8)(x+12) = 0
x = 8 or x is a negative
her first speed was 8 mph
her return speed was 24 mph
check:
6/8 + 6/24 = 1 , that's good!
