We know that 60 minutes = 1 hour and 1 mile = 5280 feet. We just need to multiply and simplify:
651 miles/hour = 651 *5280/60 feet/minutes = 651*88 feet/minutes = 57288 feet/minutes

Given the equation:
cos²(x) + 9cos(x) = 5cos(x) + 5
cos²(x) + 9cos(x) - 5 cos(x) - 5 = 0
cos²(x) + 4cos(x) - 5 = 0
[cos(x) + 5][cos(x) - 1] = 0
cos (x) = - 5 x ∉ ℝ; so:
cos (x) = 1
Then;
x = 0, and x = 2π
