1 answer:
<h3>The least common denominator is 24</h3>
<em><u>Solution:</u></em>
Given that,
We have to find the least common denominator
The denominators are 6, 8
List all prime factors for each number.
Prime Factorization of 6 is:
2 x 3
Prime Factorization of 8 is:
2 x 2 x 2
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
2, 2, 2, 3
Multiply these factors together to find the LCM
LCM = 2 x 2 x 2 x 3 = 24
Thus the least common denominator is 24

Answer:
15 miles
Step-by-step explanation:
Let be the miles in the circular park path,
the time Louisa takes to finish and
the time Calvin takes to finish both in hours.
Then , the longitude is equal to the velocity times the time used to finish. So
And the difference between Louisa's time and Calvin' time is 30 minutes, half an hour. So:
Three equations, three unknowns, the system can be solved.
Equalizing the equation with x :
In this last equation replace with the other equation and solve:
With Louisa's time find x:
