If the track is 10km long, and X travels at 40 km/h, it will take 1 hour to do 4 laps. this means that car X will do one lap in 15 minutes. Y travels at 30 km/h, which means it will do 3 laps in 1 hour, meaning that car X will do 1 lap in 20 minutes.
X- 15, 30, 45, 60
Y-20, 40, 60
Therefore, after an hour, they will pass again.
if you draw it out, it is a vertical rectangle
height of rectangle= 1-(-4)= 5units
length of rectangle= 4-2= 2units
area of rectangle =2×5= 10units^2
The answer is d because you just need to multiply AB by 4
