Answer: The speed of Ben, x= 25m/s
Step-by-step explanation:
Key concept: Ben rides 100 m and Emma rides 76 m in the same time.
Step 1: Suppose, the speed of Ben is x m/s.
Since the speed of Ben is 6 m/s greater than the speed of Emma,
So the speed of Emma would be (x-6) m/s.
Step 2: Calculate time for each and equate them as follow:
100/x= 76/(x-6)
After cross multiplying, we get:
100(x-6)=76x
100x-76x=600
24x=600
x= 25

Answer:In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate, x, is x2 − 4x + 7.
