Question

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?

Answer 1

Answer:

Number of miles traveled by Mary to work = 7 miles

Step-by-step explanation:

total distance traveled on the Map by Mary = 1 + 2.5 = 3.5 cm

Scale of the map = 2 cm = 4 miles

Hence 3.5 cm = (3.5 x 4) ÷ 2 = 7 miles

Answer 2

Answer:

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
