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:
- s =d/t
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
