Answer:
Step-by-step explanation:
- Speed of the boat = x
- Speed of the current = y
<u>Travel downstream, speed is:</u>
<u>Travel upstream, speed is:</u>
<u>Add up the equations:</u>
- x + y + x - y = 30 + 20
- 2x = 50
- x = 25
<u>Find y:</u>
Speed of the boat is 25 mph
Speed of the current is 5 mph

Answer:
9. x = 5
10. AD = 7
Step-by-step explanation:
As shown in the diagram, BD is a perpendicular bisector. And D is a point on the perpendicular bisector, meaning it is equidistant from the endpoints on the segment(points A and C). Because of this, we can say AD = CD.
We can substitute to get:
2x - 3 = x + 2
And simplify and solve:
x - 3 = 2
x = 5
AD is just 2x - 3, so we can substitute in x to find AD:
AD = 2(5) -3
AD = 10 - 3
AD = 7
