Answer: 76 miles per hour
<u>Step-by-step explanation:</u>
east bound: t = 4, r = x - 18
west bound: t = 4, r = x
d = r * t
680 = 4(x - 18 + x)
680 = 4(2x - 18)
170 = 2x - 18
188 = 2x
94 = x
eastbound: x - 18 = 94 - 18 = 76
Answer:
Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.

Given:
Volume of cubical tank = 
cubic meters.
To find:
The length of a side of the water tank.
Solution:
The volume of a cubical tank is:
Where, a is the side length.
It is given that the volume of cubical tank is cubic meters. So,
Taking cube root on both sides, we get
Therefore, the length of a side of the water tank is 2 meters.
