the complete question is
Find two numbers whose difference is 46 and whose product is a minimum
Let
x------->larger number
y-------> smaller number
P-------> product of the two numbers
we know that
-----> equation 1
-----> equation 2
substitute equation 1 in equation 2
using a graph tool
see the attached figure
Find the value of x for that the product P is a minimum
the vertex is the point
that means, for
the product is a minimum
find the value of y
therefore
the answer is
the numbers are and
Song A has 1 .10 beats/second and song B has 1.16 beats/second so it is song a.
There would be 868 steps. since there is 245 MORE steps in castle be than in castle a, you would have to add 623 to 245
