There are about 1.6×103 meters in a mile. About how many miles are there in 3.52×107 meters? Write your answer in scientific notation, expressed to the exact decimal place.

Answer 1

To find the number of miles in 3.52×107 meters, we need to divide 3.52×107 meters by 1.6×103 meters per mile.

3.52×107 meters ÷ 1.6×103 meters per mile = (3.52 ÷ 1.6) × (107 ÷ 103) miles

Simplifying further:

= 2.2 × 104 miles

Expressed in scientific notation to the exact decimal place: 2.2×104 miles.
