Answer:
B is (7,3)
Step-by-step explanation:
Solve for the x-coordinate:
(3+x)/2=5
3+x=10
x=7
Solve for the y-coordinate:
(-8+y)/2=-2.5
-8+y=-5
y=3
So the coordinates of B are (7,3)

Step-by-step explanation:
First convert the hours to minutes
now change the 900mins to seconds
as
<span>Wanda started walking along a path 27 seconds before Dave. Wanda walked at a constant rate of 3 feet per second. Dave walked along the same path at a constant rate of 4.5 feet per second. How long after Dave starts walking will he catch up with Wanda ?
***
let x=travel time of Dave
x+27=travel time of Wanda
speed*travel time=distance (same for both Wanda and dave)
..
4.5x=3(x+27)
4.5x=3x+81
1.5x=81
x=54
How long after Dave starts walking will he catch up with Wanda ? 54 sec</span>
