Answer:

The Pacific plate travels approximately 107 km in a million year.

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)  

R = d/t    

To calculate it in millimeters per year we need to convert it:  

1 km = 1000 m  

1 m = 100 cm

1km = 100,000 cm

We know by the theory that the Pacific plates might be moving approximately between 10.6 - 10.75 cm/year.  So, we might say that it moves 10.7 cm/year. So,

The Pacific plate moves 10.7 cm in one year

1 year-------------------------------- 10.7 cm

1,000,000 years ----------------- X = 10700000 cm

100,000 cm -------------- 1 km

10700000 cm -----------X = 107 km.  

The Pacific plate moves approximately 107 km/my.
