Answer:
The side length is 11 inches
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
1331 in ^3 = s^3
Take the cube root of each side
(1331 in ^3 ) ^1/3 = s^3 ^ 1/3
11 in = s
There’s no question here!
Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km
