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