Vaimiti walks at a constant pace of 1.1 m/s and takes 25 minutes to get to school. Jabril walks at 1.3 m/s and takes 30 minutes to get to school.
What is the difference between the distances they walked?

PLEASE HELPP

To solve this we first of all need to find the distances travelled by both Vaimiti and Jabril and then we will find their difference...

Let's start solving ~

Time taken by her = 30 minutes = 30×60 = 1800 seconds

➪ Therefore, The difference between distance travelled by them is 690 meter...~

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
