The distance is D. 21.25 ft.
Step-by-step explanation:
This is an example of a distance problem: <em>Find the distance traveled by an object during certain time period if the velocity of the object is known at all times.</em>
We are given a table of values for time and speed

If the speed remains constant, then the distance problem is easy to solve by means of the formula
distance = speed x time
Therefore, the total distance is

Answer:
x = 7.5
Step-by-step explanation:
Given
- 15 =
( multiply both sides by - 0.5 to clear the fraction )
- 15 × - 0.5 = x
