Answer:
3 feets
Step-by-step explanation:
Given that :
Entire walkway uses 6 feets of brick
Width of walkway = x
Width of walkway is the same along both sides ;
SINCE, the number of sides of the walkway = 2 and each side is the same
Hence,
x + x = 6 feets
2x = 6 feets
x = 6 feets / 2
x = 3 feets
The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.
<h3>What is speed?</h3>
Speed can be calculated as the ratio of distance traveled to the time taken.
The speed that a tsunami can travel is modeled by the equation
s = 356√d, where s is the speed in kilometers per hour and d is the average depth of the water in kilometers.
S = 356√d
200 = 356√d
√d = 200/356
= 0.5618
d = 0.5618^2
= 0.316 km
d = 0.32 km.
Thus, The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.
