Acity bus drives 3 3/4 of a mile between every stop. it takes the bus a quarter of an hour to travel from one stop to the next. calculate the unit rate im mph

First, let's get the units cleared:

mph = miles per hour

a quarter of an hour: 0.25 or 1/4 hour

To find the answer, we need to know how long the city bua can travel in an hour.

We can set up an equation to do so:

Let the miles it can drive in an hour be y.

1/4y = 3 3/4

1/4y = 3×4+3/4

1/4y = 15/4

y = 15/4 x 4

y = 15

Therefore, the mph of the city bus is 15 mph.

Hope it helps!

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
