Okie, so, each cm that measures across the pond is equivalent to 2ft
1cm=2ft
so if we have 3 cm
we would do 3x2
3x2=6
The diameter of the pond is 6 ft<span />
Answer:
Unicorn A is 300 years old
Unicorn B is 20 years old
Explanation:
15x + x = 320
16x = 320
x = 20
15 * 20 + 20 = 320
165/3=55 mph
650/55=h
650/(165/3)=h
(650*3)/165=h
3/165=h/650
h/650=3/165
so it is the third option
