Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer.

valentinak56 [21]

Answer:

1,225 miles = 77616000 inches

Step-by-step explanation:

It is asked to find the number of inches in 1,225 miles

Given

1 inch ≈ 1.578 × 10^-5 miles

Therefore, 1 mile = 63360 inches

Therefore, 1,225 miles = 1225 x 63360 inches

1,225 miles = 77616000 inches

or 1,225 miles = 7.7 x $10^{7}$ inches

Therefore the final answer is

1,225 miles = 77616000 inches

or 1,225 miles = 7.7 x $10^{7}$ inches
