So bigest to smallest? 1/2, 1/5, 1/6.
If the other way, just flip it around.

Answer:
1/6 mph
Step-by-step explanation:
To find miles per hour, divide miles by hours.
(1/8 mi)/(3/4 h) = (1/8×4/3) mi/h = 1/6 mi/h
The snail's speed is 1/6 miles per hour.
The answer:
first of all, we should know that the expression of a vector V (a, b) can be written as follow:
V = r (Vx i + Vyj), where r is the length of the vector, it is r = sqrt(V²x + V²y)
Vx is the component lying on the x-axis and Vy on the y-axis
<span>v ⃗ lies in Quadrant II, means Vx is less than 0 (negative)
</span>
so Vx= -r sin30° and Vy= rcos30°
r= <span>‖v ⃗ ‖=4√3
</span>
so we have v = - 4√3sin30° i + 4√3 cos30° j
the components are
v(- 4√3sin30°, 4√3 cos30°) = (-2√3, 4√3 cos30°)
