How Long Are These Natural Wonders?

[r-soy]

Find the height or length of these of these natural wonders in kilometers , meters , and centimeters .


(a)The longest cave system in the world is the Mammoth Cave system in Central Kentucky. It has a mapped length of 384 miles

(b)In the United States , the waterfall with the greatest single drop is Ribbon Falls in California which drops 1 612 ft

(c)Mount McKinley in Alaska is America's highest mountain at 20 320 feet

(d)The deepest canyon in the United States is King's Canyon in California with a depth of 8 200 ft.
-------------------------------



a) we have 384 miles as the lenth of cave

As we know 1 mi = 1609 m

then 384 X 1609 m

= 559.93

now we change to kilometers , meters , and centimeters .



559.93 X 1000 m

= 559930

559930 X 100 cm

=55993000 cm

------

(b)



1 ft = 0.3048 m

1 612 ft = 1 612 X 0.3048

=491.3376

491.3376 x 1000 m

4913376

4913376 X 100 cm

4913376

then 384 X 1609 m

= 559.93

559.93 is not what you get when you multiply 384 by 1609.

now we change to kilometers , meters , and centimeters .



559.93 X 1000 m

= 559930

559930 X 100 cm

=55993000 cm

(b)



1 ft = 0.3048 m

1 612 ft = 1 612 X 0.3048

=491.3376

You are omitting units.
1 612 ft = 1 612 ft X 0.3048 m/ft = 491.3376 m. (The ft units cancel.)

491.3376 x 1000 m

What are you trying to do here? The length 491.3376 is already in meters. To convert to km, multiply by 1km/1000m. Don't forget the units!
