alina is able to swim at a rate of about 2.5 miles per hour. talia is able to swim at a rate of 1.8 meters per second. which statement comparing the two swimmers is accurate?

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the answer is 64 cm
