A moving walkway at the airport moves at a pace of 1.8 feet per second. If you stand on the walkway as it moves, how long will i
miv72 [106K]

Answer:

150 seconds

Step-by-step explanation:

use the velocity equation of

V=\frac{delta(D)}{Delta(T)\\}

Where V is in feet per second, Delta D represents the change in displacement and delta t represents the change in time

all you need to do is rearrange the equation to find Delta(T)

as such...

Delta(t)*V=Delta(D)\\Delta (t)=\frac{Delta(D)}{V}\\Then\ insert\ your\ corresponding\ values\\\Delta(t)=\frac{270 ft}{1.8 feet/sec}  \\Delta (t)= 150sec

Given square WXYZ. If ZY = 20, find WV. Write your response in the form WV=_____.
Citrus2011 [14]

Answer:

14.14

Step-by-step explanation:

Recall :

The sides of a square are always equal ;

Since all sides are equal, the the diagonal of the square will be :

XZ² = XY² + WX²

XZ² = 20² + 20²

XZ² = 400 + 400

XZ² = 800

XZ = √800

XZ = 28.28

WY = XZ

WV = 1/2 WY

WV = 1/2 * 28.28

WV = 14.14
