Johans speed is 750-538=212 miles per 4-3=1hour. So in 4 hours he drove
The right answer for the question that is being asked and shown above is that:
x = k (1/y)
k = xy
x1y1 = x2y2
8*10 = 6y2
80 = 6y2
y2 = 40/3
So the answer is 40/3
<span>X varies inversely with y and x = 8 when y = 10, what is the value of y when x=6</span>
Perimeter = 2L + 2W → 240 = 2L + 2W → 120 = L + W → 120-L = W
Area = L x W → Area = L(120-L) → Area = 120L - L²
Find the derivative: dA/dL = 120 -2L → 0 = 120 - 2L → L = 60
Area = 120L - L² = 120(60) - (60)² = 7200 - 3600 = 3600
The maximum area is 3600 yds²
