Answer:

R = 16mm/y  

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:

<em>1 km = 1000 m </em>

<em>1 m = 100 cm </em>

<em>1cm = 10mm</em>

<em>1 km = 1,000,000 mm   </em>

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y
