A vehicle moving at the speed of t
120km per hour crosses a building in
24 seconds. What is the length of the
vehicle.

Hi,

Formula for distance is:

d = v·t, where v is the velocity (a constant value, measured in m/s), and t is time of movement, measured in s, seconds.

1 km = 1000 m, and 1 h = 3600 seconds, therefore:

v = 120 km/h = 120 000 / 3600 m/s = 33.33 m/s, so v = 33,33 m/s.

t = 24 seconds.

d = v·t = 33,33 m/s · 24 s = 100·24/3 = 800 m.

So, building is 800 meters long.

Have you understood the solution ?
