Alina swims at a rate of 2.5 miles per hour. tailia is able to swim at a rate of 1.8 meters per second. which one swims faster

Alina

Step-by-step explanation:

2.5 miles per hour is Alina so you have to convert meters into miles so Tailia swam 0.00111 miles for short and then times it by 60 which is 0.00223 for short so that is a minute then times it by 60 again which is 0.134 miles for short in an hour. So Alina swam faster because she swam a longer distance than Tailia in an hour

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
