I’ll assume the rate is 4 cm/year (typical for plate motion). Time = distance / speed.
Convert distance: 10,000 km = 10,000 × 1000 m × 100 cm = 1×10^9 cm.
t = (1×10^9 cm) / (4 cm/yr) = 2.5×10^8 yr = 250 million years.
Notes:
- If both plates are moving toward each other at 4 cm/yr, the relative speed is 8 cm/yr and t = 125 million years.
- If the rate meant 4 mm/yr instead, the times would be 2.5 billion years (one plate) or 1.25 billion years (both).
