If we develop energy sources which do not use coal, using scientific research, our reliance on coal is diminished; for if we have a technology that doesn't use coal, we don't need to use coal.

How to solve such time related questions?

The key concept for solving such questions is the relationship between speed, distance and time.

The relationship between them is Distance = Speed x Time

Given:-

Total time taken by girl to complete the trip = 15 minutes = $\frac{1}{4}$ hours

Speed while riding going = 6 miles per hour

Speed while coming back = 4 miles per hour

Total time taken by girl =

Time taken while going + Time taken while coming back - (1)

Let x be distance from home to store

$\frac{x}{6}$ = Time taken while going

$\frac{x}{4}$ = Time taken while coming back

Substituting in (1) we get

$\frac{1}{4} = \frac{x}{6} + \frac{x}{4}$

$\frac{1}{4} = \frac{2x + 3x}{12}$

$\frac{1}{4} = \frac{5x}{12}$

$x= \frac{12}{20}$

x = 0.6 miles

Thus home is 0.6 miles away from the store

A) Enter the corresponding values on the quadratic formula:

ollegr [7]

The answer is a = 0, b = -5, and c= 39.

Step-by-step explanation:

step 1 :

A quadratic equation means that it should have at least one squared term.

step 2 :

The standard form is ax² + bx + c = 0.

step 3 :

The solution to the quadratic equation is usually written in the form

x = (-b ± √(b2 − 4ac))/(2a)

where a = coefficient of x^2

b = coefficient of x

c = constant term

step 4 :

The given equation is -5x +32.

∴ The answer is a = coefficient of x^2 = 0

b = coefficient of x = -5

c = constant term = 39
