Answer

Explanation:

Step1: Convert miles to centimeters

We know 1 mile = 5280 feet, 1 foot = 12 inches and 1 inch = 2.54 centimeters. So for 3 miles: [3\times5280\times12\times2.54 = 3\times5280\times30.48=482803.2\text{ cm}]

Step2: Convert years to days

Since 1 year = 365 days, for 8 years: [8\times365 = 2920\text{ days}]

Step3: Calculate speed in cm per day

Speed (v=\frac{\text{distance}}{\text{time}}), so (v=\frac{482803.2}{2920}\approx165.34)

Answer:

165
