Answer:
50000years
Explanation:
3cm-1year. note:-1m=100cm
1500m=1500x100=150000
150000-x
cross multiply
=> 3x=150000x1
=> x=150000/3
=> 50000years

Given:
Average Speed = 3cm
Total speed = 1500cm
To Find:
Total time taken to drift apart
Solution:
Average speed is calculated from the change in displacement divided by the elapsed time.
v = Δs/Δt or
Δt = Δs/v
= 1500/3 × 100/m
= 150000/3
= 50000
= 5 × 10`4
Answer: The total time taken is 5 × 10`4 years
