Arc length is angle times radius. The unit circle has radius 1, so the arc length is just π/3
Answer:
<em>2.5 hours</em>
<u>Skills needed: Speed, distance, time problems</u>
Step-by-step explanation:
1) We are given speed and distance, and have to find out the the time (in hours).
- In terms of units, everything is matched up (Since distance and speed use kilometers, and speed and time use hours).
- Time is always the distance you travelled (how far) divided by how fast you travelled (the rate/speed)
---> We can use the formula for time:
t= time
d=distance
r=rate/speed
2) Now, let's plug in for distance and rate.
--->
2.5 hours is the answer.
Aloha!
I was wondering what are the choices or numbers?
I am great at math so I can help you and long as u give the answers.
You would write it as (1/10^12)
any negative exponent does the same thing
ex: x^-1 turns into (1/x^1)
