Question

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.


Part A

According to the question, the unit rate is to be expressed in which units?

Answer: miles per hour


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: 3/4 / 1/6 miles/hour.


part c submit without answer oof


Part D

Rewrite the fractions using the least common denominator (LCD) you found in part C.

Answer: 2/12

I need answer for E

Part E

Rewrite the complex fraction as a division problem that reads left to right.


i need answer for F

Part F

To divide 9/12 by 2/12, answer this question: How many sets of 2/12 are in 9/12? Use the model representing the fraction 9/12 to help you answer the question. (Hint: Think about grouping the blue boxes into pairs.)


I need answer for G

Part G

To divide two fractions with common denominators, divide the first numerator by the second numerator, ignoring the denominators. Rewrite this division problem as the division of two integers.


i need answer for H

Part H

Solve the division problem to find Selma’s unit rate in miles per hour. Write your final answer as a mixed number.


i need answer for I

Part I

Express your answer to the problem as a sentence. Be sure to include the correct units.

Answer 1

Answer:

Selma's speed for Monday's run is ,

$4 \dfrac {1}{2}$ mile/hour

The other answers are given below.

Step-by-step explanation:

Selma's speed or unit rate in miles per hour for Monday's run is,

$\frac {\frac {3}{4}}{\frac {1}{6}}$ mile/hour

= $\frac {9}{2}$ mile/hour

= $4 \dfrac{1}{2}$ mile/hour

A. mile/hour

B. $\frac {\frac {3}{4}}{\frac {1}{6}}$ mile/hour

C. question incomplete

D.  $\frac {9}{2}$ mile/hour

E. (3/4) ÷ (1/6)

F. There are $\frac {\frac {9}{12}}{\frac {2}{12}}$  or $4 \dfrac {1}{2}$  sets of 2/12 in 9/12.

G. $\frac {\frac {9}{12}}{\frac {2}{12}}$

= $\frac {9}{2}$

H. Selma's unit rate in mile per hour,

= $\frac {9}{2}$ mile/hour

= $4 \dfrac {1}{2}$ mile/hour

I.  Selma's speed for Monday's run is,

  $4 \dfrac {1}{2}$ mile/hour
