Answer: 8 minutes to 28 minutes

Step-by-step explanation:

To include 95% of all employees, it will be 2 standard deviations from the mean. Two above and two below. Each is 5 min. So add 10 and subtract 10 from 18.

On the Gaussian Curve, about 68.3% are included within the first standard deviation above and below the mean. Then about 27.2% are added in the second standard deviation.

Just add a similar triangle from the opposite side

Then what happens

  • Hypotenuse of this triangle becomes common and diagonal of the rectangle.

Now

For question 1:

Calculating the speed between A and B:

Time\ (t)= 1 \ hours\\\\Distance\ (d)= 10 \ km\\\\V=\frac{d}{t}=\frac{10}{1}= 10 \ kmph

For question 2:

Calculating the speed between B and C:

Time\ (t)= (2-1)=1 \ hours\\\\Distance\ (d)= (15-10)= 5\ km\\\\V=\frac{d}{t}=\frac{5}{1}= 5 \ kmph\\  

For question 3:

In this the speed between A and B is the double to speed between B and C.
