Can anyone help here? I am hung up on these few

y varies inversely as vx. y = 25 when x = 16. Find y when x = 25. y The amount of time it takes a swimmer to swim a race is inversely proportional to the average speed of the swimmer. A swimmer finishes a race in 37.5 seconds with an average speed of 4 feet per second. Find the average speed of the swimmer if it takes 25 seconds to finish the race. O A. 7 feet per second O B. 6 feet per second O C. 5 feet per second O D. 8 feet per second Solve the inequality and graph the solution set on a number line. - 21 sx - 20
