## Homework Statement

A jetskier is moving at 8.30 m/s in the direction in which the waves on a lake are moving. Each time he passes over a crest, he feels a bump. The bumping frequency is 1.17 Hz, and the crests are separated by 5.30 m. What is the wave speed?

Jetski's Speed = 8.30m/s with the waves

ƒ of waves= 1.17

wavelength = 5.30m

## Homework Equations

v = (wavelength)ƒ

## The Attempt at a Solution

when i tried the equation above i got an answer of 6.201m/s which turned out to now be right. What am i missing here?

v = ƒ(wavelength)

v = (1.17)(5.30)

v = (6.201m/s)
