The international border between the United States and Mexico is approximately 1.951 × 103 miles in length. What is this distance in standard form?

Question

A.
1,951 miles
B.
195.1 miles
C.
195,100 miles
D.
19,510 miles

Answer 1

To convert \( 1.951 \times 10^3 \) miles into standard form, we need to understand what \( 10^3 \) means.

\( 10^3 \) equals 1000, so:

\[ 1.951 \times 10^3 = 1.951 \times 1000 = 1951 \]

Thus, the distance in standard form is:

A. 1,951 miles
