Answer:
<u>1.16 m (approximately)</u>
Step-by-step explanation:
Let x be the width of the path.
Total area = (5+2x)(3+2x) = 39
Expand and simplify
4x²+ 16x+15-39 = 0
4x² + 16x - 24 = 0
Simplify
x² + 4x -6 = 0
Rational factoring does not work, so use quadratic formula
x = +/- sqrt(10) -2
= 1.16 or -5.16 (reject)
= <u>1.16 m (approximately)</u>
So 10.4mi = 1 hour
We need to find out how many miles 1.2 hours is.
1.) Well, the first step would be to multiply 1.2 on both sides of:
10.4mi = 1 hour
because that would make this number of miles is = to 1.2 hours which is wha we're looking for
1.2(10.4) mi = 1.2 hour
2.) Simplify
12.48 mi = 1.2 hour
3.) That means Gina rides 12.48 miles each day if she rides for 1.2 hours each day at a pace of 10.4 miles per hour :)
4/11 * 10/8
= 1/11 * 10/2
= 1/11 * 5
= 5/11
answer 5/11
you got it correct
