What the statement above is saying is the following: 
(3/4)n = 5/8

Solve for n. 

3n/4 = 5/8

Is another way to write the above statement.

Multiply 4 on both sides.

3n = (5*4)/8
3n = 20/8

Divide 3 on both sides to solve for n. 

n = (20/8)/3
n = (20/8*3)
n = 20/24

Simplify!

n = 5/6

Nick jumps off a cliff. It takes him 2.2 s to hit the water below. What is the height of the cliff? g=9.8 m/s2
Marta_Voda [28]

Answer:

9.8 x 2.2 =  21.56 m

distance = time x speed

speed = distance ÷ time

Step-by-step explanation:

The highest point he reached occurred at the vertex, which is at t = -b/2a = 2.2 second. Plugging in t = 2.2

9.8 x 2.2 =  21.56ft

Higher cliffs don't accelerate your fall -- acceleration is constant during free fall. The pull of gravity decreases infinitesimally at higher elevations, but it pulls you with an equal force from the first second of your jump until you decelerate when you hit the water.
