To convert the number 15,300 miles into scientific notation, we need to express it in the form \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.
1. The number 15,300 can be rewritten as:
\[
15,300 = 1.53 \times 10^4
\]
(We move the decimal point two places to the left, which corresponds to a positive exponent of 10).
Thus, the correct representation of 15,300 miles in scientific notation is:
**1.53 x 10^4**
