The distance in miles from P to Q is 12 miles
<h3>Distances and speed</h3>
Let the distance from P to Q be "d"
Since the formula for calculating speed is expressed as:
For the distance of P to Q
40 = d/t
d = 40t
If he drives back at an average speed of 45mph and 2 mintes less, then;
45 = d/t - 0.033
d = 45 (t - 0.033)
Equating both distances
40t = 45(t - 0.033)
40t = 45t - 1.485
-5t = -1.485
t = 0.297
Get the distance from P to Q:
d = 40(0.297)
d = 11.88 miles
Hence the distance in miles from P to Q is 12 miles

There are a total of Forty seven questions in the math section of the psat.
Given that the manager wants to know the type of vegetarian dishes that the people prefer, the sample that is going to provide him with the most accurate data is:
- a random group of 40 people on the street
The reason for this is because this sample has the most number and the people that are used for the sampling were chosen randomly.
A random sampling is very good because it provides an opportunity for every member of a population to be selected.
