Given that the ship was traveling for 4 mph faster heading west than south then let the speed of the ship heading south be x mph, the speed of the ship heading west will be (x+4) mph
the distance is given by:
distance=speed*time
distance heading south was:
x*4=4x miles
distance heading west was:
5(x+4)=5x+20
thus the total distance will be given by:
4x+(5x+20)=191
9x+20=191
9x=191-20
9x=171
x=171/9
x=19 mph
the speed the ship used to travel west was:
x+4
=19+4
=21 mph
Answer:
Based on the model,the length of the wall is <u>9/8</u> ft, the width of the walk is 1/2 ft, and the height of the wall is <u>11/8</u>. The volume of the portion of security wall that Tim has constructed so far is <u>99/128</u> cu ft.
Step-by-step explanation:
In the picture attached, part of a security world castle is shown.
length: 9 blocks, which is equivalent to 9*(1/8) = 9/8 ft
height: 11 blocks, which is equivalent to 11*(1/8) = 11/8 ft
width: 1/2 ft
Volume: length*height*width = (9/8)*(11/8)*(1/2) = (9 * 11 * 1)/(8 * 8 * 2) = 99/128 cu ft
