Answer:Kimo is 17 years old and Jennifer is 13 years old.
Step-by-step explanation:
Let x represent Kimo's current age.
Let y represent Jennifer's current age.
Nine years ago, Kimo was twice as old as Jennifer was then. It means that
x - 9 = 2(y - 9)
x - 9 = 2y - 18
x = 2y - 18 + 9 = 2y - 9
In four years, Jennifer will be the same age that Kimo is now. It means that
x = y + 4 - - - - - - - - - 1
Substituting x = 2y - 9 into equation 1, it becomes
2y - 9 = y + 4
2y - y = 4 + 9
y = 13
x = 2y - 9 = 2 × 13 - 9
x = 17

Distance between the top and bottom of the bridge is 76 feet
Solution:
The image of the question is attached below.
Ratio of the triangles is 1 : 1.
AC = 2x + 10 and EC = 4x − 18.
Since the two triangles ACB and DCE are in the ratio 1 : 1, so their corresponding sides are also in the ratio 1 : 1.
Therefore sides AC and EC are corresponding to each other.
AC : EC = 1 : 1



Subtract 10 from both sides of the equation.

Subtract 4x from both sides of the equation.

Divide by -2 on both sides, we get
⇒ x = 14
Distance between the top and bottom of the bridge is EA.
EA = AC + EC
= 2x + 10 + 4x - 18
= 6x - 8
= 6(14) - 8
= 84 - 8
EA = 76 feet
Distance between the top and bottom of the bridge is 76 feet.
