The distances in a children’s traithlon are swimming 1/4 mile, running 3/4 mile, and biking 3/4 mile. what is the total length of the race?
a.7/12
b.1 1/2
c.1 3/4
d.2 1/4

C

Step-by-step explanation:

1/4+3/4+3/4= 7/4

Now, we need to express as a mixed number.

7/4 = (4+3)/4 = (4/4) + (3/4) = 1 + 3/4 = 1 3/4

Answer C.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
