Answer:
The distance of the run was 27 miles and the distance of the bicycle race was 88 miles.
Step-by-step explanation:
Since I have entered 115-mile biathlon that consists of a run and a bicycle race, and during my run, my average velocity is 9 miles per hour, and during my bicycle race, my average velocity is 22 miles per hour , and I finish the race in 7 hours, to determine what is the distance of the run and what is the distance of the bicycle race, the following calculations must be performed:
7 x 22 + 0 x 9 = 154
5 x 22 + 2 x 9 = 128
4 x 22 + 3 x 9 = 115
Therefore, the distance of the run was 27 miles and the distance of the bicycle race was 88 miles.

Answer:
Step-by-step explanation:
eq1. x + 2y = 11
eq2. 6x + 4y = 34
------------------
Objective is to eliminate one of the variables, either x or y.
Let's eliminate y by multiplying the top equation with the number 2.
2x +4x = 22
Now multiply the bottom equation by -1
2x +4x = 22
-6x -4x = -34
------------------
Now add both equation and you will see that y will be eliminated.
So therefore, the answer is A.2
