Rachel jogged along a trail that was 1/4 of a mile long. she jogged along the trial 8 times. How many miles did Rachel jog in all?



Answer :

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.
