Answer:
The sidewalk is 2 feet wide
Step-by-step explanation:
The area of the sidewalk is given as 80 square feet
The length and width of pool
including side walks will be;
10 + 2x and 6 + 2x
To get the area of the side walk
That will be area of total minus area of the pool
That will be ;
(10 + 2x)(6 + 2x) - 10(6) = 80
60 + 12x + 20x + 4x^2 - 60 = 80
4x^2 + 32x -80 = 0
x^2 + 8x -20
x^2 + 10x - 2x - 20 = 0
x(x + 10) -2(x + 10) = 0
(x-2)(x + 10) = 0
x = 2 or -10
since width cannot be negative;
The sidewalk is 2 feet wide

Answer:
Step-by-step explanation:
1 hour = 60 minutes
1 kilometers = 1000m
9 kilometers = 9*1000 = 9000 m
Distance traveled in 60 minutes = 9000 m
Distance traveled in 1 minute = 9000/60
Distance traveled in 30 minutes
= 4500m = 4.5 km
