find the distance if the scale is 3 cm: 5 mi.

Question

19. 18 cm
20. 25 cm

Answer 1

For both 19 and 20, we need to set up a proportion:

3 cm / 5 mi = x cm / distance

Solving for distance:

distance = (5 mi * x cm) / 3 cm

For 19:
distance = (5 mi * 18 cm) / 3 cm = 30 mi

For 20:
distance = (5 mi * 25 cm) / 3 cm = 41.67 mi (rounded to two decimal places)
