Ostrovityanka [42]

Answer:

no they are not equivalent

Step-by-step explanation:

0.4/15 = 0.026

so for every minute they travel 0.026km

0.6/20 = 0.03

so for every minute they travel 0.03km

A cabbage palmetto has a height of 80 feet. what is the approximate height of the tree in meters?
frutty [35]
1 foot is about 0,3 meters.
If the height of the cabbage palmetto is 80 feet, it should be about 80*0,3 = 24 meters.

So a cabbage palmetto with 80 feet of height is about 24 meters.

Hope this helps! :)
