We’ll subtract the exponent in the denominator from the exponent in the numerator, keeping the base the same. Cant be simplified, because the base of the expression in the numerator is y and the base of the expression in the denominator is x.

Jeremy's father drives him to school in rush hour traffic in 20 minutes. One day there is no traffic, so his father can drive hi
nexus9112 [7]
Hello.

Let's call the initial speed 'x'. When driving at that speed, Jeremy's father takes 20 minutes to arrive to the school. When driving 18 mph faster (x + 18), he gets there in 12 minutes. Therefore:

20 - x
12 - x + 18

As they're inversely proportional:

12 - x
20 - x + 18

\frac{12}{20} = \frac{x}{x+18}
12x + 216 = 20x
216 = 8x
x = \frac{216}{8}
x = 27

That means that the initial speed is of 27mph. Since we have the time and the speed, we can find the distance:

Average Speed = Total Distance Travelled / Time Interval

20 minutes = 0.33h

27 = \frac{Distance}{0.33}
Distance = 27.0.33
Distance = 12.21 miles

Hope I helped and good luck.
