Answer:

• 1.86×10^5 mi/s
• 6.71×10^8 mi/h

Explanation:

In scientific notation, the decimal point is placed immediately to the right of the most-significant digit. The exponent of 10 is the number of digits to the right of the most significant digit.

186,000 mi/s = 1.86×10^5 mi/s

671,000,000 mi/h = 6.71×10^8 mi/h
