Answer:
the exact answer is 1.98
if we rationalize denominator we get root 0f 10 times pi divided by 5
root of 10 is about 3.1 () so we have
≈ 9.6/5 = 1.92
Step-by-step explanation:

If a bus with an average speed of 40 miles per hour travels for 30 minutes, how far will it have gone?
2 answers:
In this question, it is given that
If a bus with an average speed of 40 miles per hour travels for 30 minutes.
Here time is 30 minutes. And 1 hour have 60 minutes. SO the given times is 0.5 hour .
And the speed is 40 miles per hour .
We have to find the distance. And distance is the product of speed and time. That is

To find conjecture about regular polygon, use the formula 
Where, n = number of sides of the regular polygone
1) Triangle
n =3
So, Conjecture of the triangle =
= 120
2) Square
n =4
So, Conjecture of the square =
= 90
3) Pentagone
n = 5
So, Conjecture of the pentagon =
= 72
4) Hexagone
n = 6
So, Conjecture of the pentagon =
= 60.
