Ellen and Oscar are running in a race. Ellen runs the first mile in 8 minutes, and then each additional mile in 11
minutes. Oscar's speed is represented by the equation t = 10m, where t is the number of minutes it takes him to run m
miles.

Which statement is true?

A. If the race is 4 miles long, Ellen finishes ahead of Oscar.

B. If the race is 3 miles long, Ellen and Oscar finish at the same time.

C. If the race is 2 miles long, Oscar finishes ahead of Ellen.

D. If the race is 1 mile long, Oscar finishes ahead of Ellen.

YES THIS IS A GOOD QUESTION LET ME SOLVE THEN I WILL EDIT THE ANSWER :)

asnwer is (g o h o f)(x) = 2x - 6/x + 7

step-by-step explanation:

given,

f(x) = x - 3/x

g(x) = x + 3

h(x) = 2x + 1

we need to find : (g o h o f)(x)

we can write (g o h o f)(x) = g[ h{ f(x) } ]

so first we find h{f(x)}

h{f(x)} = f(x) + 3 = (x - 3/x) + 3

h{f(x)} = x - 3/x + 3

now we find g[ h{ f(x) } ].

g[ h{ f(x) } ] = g(x - 3/x + 3)       {plug h{f(x)} = x - 3/x + 3 in g[h{f(x)}] }

g(x - 3/x + 3) = 2 (x - 3/x + 3) + 1

                    = 2x - 6/x + 6 + 1

                    = 2x - 6/x + 7

hence we get (g o h o f)(x) = 2x - 6/x + 7
