 Question 233210: The amount of time it takes a swimmer to swim a race varies inversely as the average speed of the swimmer. A swimmer finishes a race in 400 seconds with an average speed of 3 feet per second. Find the average speed of the swimmer if it takes 300 seconds to finish the race. How do I get the answer?Answer by ankor@dixie-net.com(15661)   (Show Source): You can put this solution on YOUR website!The amount of time it takes a swimmer to swim a race varies inversely as the average speed of the swimmer. A swimmer finishes a race in 400 seconds with an average speed of 3 feet per second. Find the average speed of the swimmer if it takes 300 seconds to finish the race. : you can use an inverted ratio equation: let s = speed of the faster swimmer : = which is = cross mult 3s = 4*3 3s = 12 s = s = 4 ft/sec is the faster swimmers speed : : Prove that to yourself. the dist for both should be the same: 400 * 3 = 1200 ft 300 * 4 = 1200 ft
