I am not sure, but I think you are talking about the least square method
Call x the distance from home plate to second base.
There is a right triangle formed by homeplate, first base and second base. The sides of this triangle are 80 feet and 80 feet. The hypothenuse meets Pythagoras theorem:
x^2 = 80^2 + 80^2 = 2(80)^2
x = 80√2
Then the answer is the option D.

Step-by-step explanation:
1)X represents the time he spent in cardio.
Y represents the time he spent in weighted.
2)If you could put the options on the second one it would be better.
3)4x+y=210
3x+2y=195
y=210-4x
3x+2(210-4x)=195
3x+420-8x=195
5x=420-195
5x=225
x=45
y=30
Total time of one cardi and weighted = 75min= 5/4 h.
4)2x+4y=
90+120=210 total time of week three.
