Answer:
11.45 years
Step-by-step explanation:
22 inch ÷ 21 inch = 1.0476190476
Difference between Type A and B 12 inch
= 12 inch ÷ 1.0476190 = 11.454545
Will take 11.45 years to cover 12 inch of Type B
So,
Type B
21 inch per year × 11.45 years + 36 inch= 276.45 inch or 276 inch or 23 Feet.
Type A
22 inch ×11.45 years + 24 inch = 275.9 inch or 276 inch Or 23 Feet.
