Answer:
51 inches
Explanation:
By definition of midpoint, 42 through T + T through 60 is congruent to each other.
So, we can add 42+60 together to get the total distance. This is 102.
Next, we divide 102 by 2 because as mentioned since T is the midpoint, each "segment" is exactly 2 halves, they are congruent to each other.
102/2= 51 inches.
