Multiply the car by 2: 300 meters x 2 = 600 meters

30 seconds x 2 = 60 seconds.

The car also traveled 600 meters in 60 seconds, so the speed of the vehicles are the same.

No vehicle was faster.

$\dfrac{1}{4}=\dfrac{1*2}{4*2}=\dfrac{2}{8}$

$\dfrac{1}{4}-\dfrac{1}{8}=\dfrac{2}{8}-\dfrac{1}{8}\\$

$=\dfrac{1}{8}$
