Sagot :
The correct answer is:
2 miles.
Explanation:
The trail she jogs is 1/4 mile. She jogs it 8 times; this is 8(1/4).
To multiply a whole number and a fraction, write the whole number over 1:
8/1(1/4)
Now multiply straight across:
(8*1)/(1*4) = 8/4 = 2
She jogged 2 miles.
When the a unit of work is done in one attempt, then the total amount of work done in n attempts is equal to the n times of of a unit work. The total number of miles Rachel jogged in all is 2 miles.
Given information-
The length of the trial is 1/4 of a mile.
Total number of times Rachel jogged along a trial is 8.
Suppose Rachel jogged n miles on the trail.
How to calculate the number of amount of work?
When the a unit of work is done in one attempt, then the total amount of work done in n attempts is equal to the n times of of a unit work.
As the length of the trail is 1/4 of a mile and the total number of times Rachel jogged along a trial is 8.
To find the total number of miles she jogged we need to repetitively add the 1/4 of a mile 8 times or we can multiply 8 in the 1/4 of a mile.
Thus the number of miles Rachel jogged is,
[tex]n=\dfrac{1}{4} \times8\\n=2[/tex]
Hence the total number of miles Rachel jogged in all is 2 miles.
