Suppose two bicyclists start at the same location.
aliya0001 [1]

Answer:

  4 mi/h

Step-by-step explanation:

The distance between the cyclists is the hypotenuse of an isosceles right triangle. The hypotenuse is √2 times the length of the legs in such a triangle, so each cyclist must have ridden 8 miles in 2 hours.

Their speed is (8 mi)/(2 h) = 4 mi/h.

_____

<em>Additional comment</em>

Consider an isosceles right triangle with leg lengths 1. Then the Pythagorean theorem tells us the length of the hypotenuse is ...

  c² = a² +b² . . . square of hypotenuse is sum of squares of legs

  c² = 1² +1² . . . . both legs are 1 in our example triangle

  c² = 2

  c = √2

That is, the hypotenuse is √2 times the leg length.

X is 2 more than y
x=2+y

5 years ago (x-5 and y-5)
sum is 30
x-5+y-5=30
x+y-10=30

x=2+y
sub 2+y for x
2+y+y-10=30
2y-8=30
add 8 to both sides
2y=38
divide both sides by 2
y=19

Lindsey is 19
