Answer:
v = 11.41 yards/second
Step-by-step explanation:
Given that,
In August 2009, Usain Bolt run 100 m in 9.58 seconds.
1 yard = 0.9144 m
It means,
100 m = 109.361 yards
We need to find Usain Bolt's average speed in yards per second.
Average speed = total distance/time taken
So, her average speed is 11.41 yards/second.
The value of x will be 3
From given diagram, triangle ABC and EDC meet at a common vertex C.
So, triangle ABC and EDC both are congruent to each other.
Applying the similarity property of congruence, ratio of the congruent triangles' corresponding sides will be equal.
Therefore,
Simplifying the expression,
We get
(18-x)/x = 25/5
(18-x)/x = 5
18-x = 5x
18-x-5x = 0
18 - 6x = 0
- 6x = -18
x = 3
Hence, the value of x is 3.
