Question

Patrick drives from p to q at an average speed of 40mph.

Answer 1

The distance in miles from P to Q is 12 miles

Distances and speed

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
