Answer:
18 minutes
Step-by-step explanation:
From the above question:
3 laps = 2 minutes
27 laps = x minutes
Cross Multiply
3 laps × x minutes = 27 laps × 2 minutes
x minutes = 27 laps × 2 minutes/3 laps
x minutes = 18 minutes

Answer:
Step-by-step explanation:
If you realize that the sin is actually the y coordinate of a (unit) circle when you travel around it, you will know that it is -1 when you are 3 quarters round, assuming you started at (1,0).
The circumference is measured in radians, where one round is 2π.
So 3/4 of 2π is 3/2 π.
In degrees, the answer is 3/4 of 360°, which is 270°.
Your answer is 245.68 . when you round off to the nearest you go to the number after what you want to round off.
