Answer: John Hancock Center is faster
Step-by-step explanation:
If the equation is y=30x and x represents seconds then multiply 30 and 60 to get the amount of feet travelled per minute which is 1800. If 1800>1400 then John Hancock Center has a faster elevator rate.
The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
