The total distance traveled  is mathematically given as

d=4.5km

What is the total distance traveled?

Question Parameters:

A compact disc has a radius of 6 cm.

the constant angular speed of 5 rev/s

time 40 min

Generally, the equation for the linear speed   is mathematically given as

v=w*r

Therefore

v=10 pi * 6

v=60pi cm/s

In conclusion, the equation of the distance

distance = v*t

d=60pi * 2400

d=452389.342 cm

d=4.5km
