Answer:
Since l and m are parallel,
let the angle next to (6x+7) be 'a'
then a will be equal to (3x - 16) since 3x-16 and a are corresponding angles
Since the 2 angles make a linear pair,
6x + 7 + 3x -16 = 180
9x -9 = 180
x -1 = 20
x = 21
Since the angles 11y-32 and 6x + 7 are vertically opposite,
11y - 32 = 6x + 7
11y - 32 = 6(21) + 7
11y = 126 + 39
11y = 165
y = 15

A is correct because Side PQ of one triangle corresponds to side ST of the other triangle since are located at the same spot.
4 / 1 = 1 / x....4 miles to 1 hr = 1 miles = x hrs
cross multiply
4x = 1
x = 1/4.....it would take 1/4 of an hr (or 15 minutes) to walk 1 mile
