Question

Bryan hiked 8.48x 105 feet last summer. There are approximately 5.3x 10 feet in

Answer 1

Answer: the number of miles that Bryan hiked is 160

Step-by-step explanation:

Total distance that Bryan hiked last summer was 8.48x 10^5 feet.

There are approximately 5.3 x 10^3 feet in a mile. Converting 8.48 × 10^5 feet to miles, it becomes

8.48 × 10^5/5.3 x 10^3

Applying the rules of indices which is expressed as

a^x ÷ a^y = a^(x - y)

It becomes

= 1.6 × 10^ (5 - 3)

= 1.6 × 10^2

= 160 miles
