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
