10. eddie and his sister walked from home to school. his sister started walking at 8.00 am at an average speed of 50 m/min. eddie started walking at 8.05 am at a speed of 60 m/min. eddie caught up with his sister at mid-point between the school and his home. find the distance between eddie's home and the school.

The distance between Eddie's home and the school is 3000 m

Step-by-step explanation:

Consider the provided information.

His sister started walking at 8.00 am at an average speed of 50 m/min. Eddie started walking at 8.05 am at a speed of 60 m/min. Eddie caught up with his sister at mid-point between the school and his home.

Let the distance between school and home is x.

Let t is the time taken by Eddie sister to reach at mid-point between school and home.

Eddie caught up with his sister at mid-point between the school and his home.

That means his sister covers x/2 distance.

Speed of Eddie sister is 50 m/min.

.....(1)

Eddie started walking at 8.05 am at a speed of 60 m/min.

.....(1)

Equate both the equation as shown:

Hence, the distance between Eddie's home and the school is 3000 m

where are the choices?

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
