PLEASE HELP ASAP!!!

Pia printed two maps of a walking trail. The length of the trail on the first map is 8 cm. The length of the trail on the second map is 6 cm. (a) 1 cm on the first map represents 2 km on the actual trail. What is the scale factor from the map to the actual trail? What is the length of the actual trail? (b) A landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm. What is the scale factor from the first map to the second map? What are the side lengths of the landmark on the second map? Show your work.

SINAZEUS
other first map each cm represents 2 km so:
[tex] \frac{1}{8 } = \frac{2000}{16000} [/tex]
so its 16 kilometers
on the second map with the same factors:
[tex] \frac{1}{6} = \frac{2000}{12000} [/tex]
its 12 km
for the A landmark:
multiply the sides by 20000 because 1km=10000mm
so the sides are 60000, 80000,100000
hope this helps
