Speed problem including the speed of sound

Homework Statement

A bowling ball traveling at constant speed hits the pins at the end of a bowling lane 16.5m long. The bowler hears the sound of the ball hit the pins 2.5 seconds after the ball is released. What is the speed of the ball?

Homework Equations

Distance=16.5m
Time=2.5 s

The Attempt at a Solution

s=d/t =16.5/2.5 =6.6m/s

how does the speed of sound effect the overall speed of the ball?

Total time t = d/Vb + d/Vs. You have assume the velocity of sound = 340 m/s. t is given.Find Vb, the velocity of the ball
