Question

1. from 139 miles to 385 miles ______ % ☐ increase ☐ decrease

Explanation:

Step1: Find the amount of change

To find the amount of change, we subtract the original value from the new value. The original value is 139 miles and the new value is 385 miles. So, the change is $385 - 139 = 246$ miles.

Step2: Calculate the percentage increase

The formula for percentage increase is $\frac{\text{Amount of Change}}{\text{Original Value}} \times 100\%$. Substituting the values we have, the original value is 139 and the amount of change is 246. So, the percentage increase is $\frac{246}{139} \times 100\% \approx 176.98\%$ (rounded to two decimal places). Also, since 385 > 139, it is an increase.

Answer:

The percentage increase is approximately $\boldsymbol{177\%}$ (or more precisely approximately $\boldsymbol{176.98\%}$) and it is an Increase.
