Answer:
<em>35 units</em>
Step-by-step explanation:
1024
1 division: 2
2 divisions: 2×2 = 4
3 divisions: 2×(2×2) = 8
The number of viruses is 2^n, where n is the number of divisions.
After 10 divisions, there are 2^10 = 1024 viruses.
(1/2 inch) / (3/4 hour) = 1/2 * 4/3 inches/hour = 2/3 inches/hour
