Step-by-step explanation:

Given

At the beginning of race you start behind your friend .

At the halfway point, you are   feet ahead of your friend.

Therefore change in distance

initially it is

at half way it is

total change

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
