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.
AFE=35 degrees because 180=55+90+x
The correct answer is BC=4.
The answer to the problem is 2300
<h3>
Answer: 6 cm^3</h3>
This is the same as saying 6 cubic cm
====================================================
Work Shown:
d = density = 4 g/cm^3
m = mass = 24 g
v = volume = unknown
--------------
d = m/v
4 = 24/v
4v = 24 .... multiply both sides by v
v = 24/4 .... divide both sides by 4
v = 6 cm^3
