Selma uses a jogging trail that runs through a park near her home. the trail is a loop that is 3/4 of a mile long. on monday, selma ran the loop in 1/6 of an hour. what is selma’s unit rate in miles per hour for monday’s run?

in this activity, you will use the common denominator method to calculate a unit rate that involves fractions. answer the questions that follow to calculate selma’s unit rate in miles per hour.

part a
according to the question, the unit rate is to be expressed in which units?

(3/4) / (1/6)= 3/4 * 6/1= 18/4 =4.5 miles per hr
so the answer is 4.5 miles per hour

i dont need the answer for a only b

part b
now, write selma’s jogging rate as a complex fraction. a complex fraction is one whose numerator, denominator, or both are fractions. be sure to include units in your answer.

answer:

9/2 miles per hours

you already had the answer when you got 4.5 hours all you needed to do was to simplify 18/4 to 9/2

answer:

below.

step-by-step explanation:

part b.

the jogging rate = distance / time taken =   3/4 / 1/6 miles/hour.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
