A map has a scale of 2 centimeters = 4 miles. Mary's drive to work is represented on the map as traveling 1cm north then 2.5 cm west. Which equation could be used to determine how many miles Mary drives to work?

Step-by-step explanation:

Given:

Scale:

2 cm to 4 miles

Mary's drive to work:

1 cm north

= 1 cm × 4 miles/2 cm

= 2 miles north

2.5 cm west

= 2.5 cm × 4 miles/2 cm

= 5 miles west

Total distance = (1 cm N + 2.5 cm W) × 4/2

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
