The speed of lifting the load with a construction crane is 2.16 km / h. What is the height of a house under construction if the load was lifted in 0.5 minutes?
Initial data: V (speed of lifting the load by a construction crane) = 2.16 km / h; t (lifting time) = 0.5 min.
SI system: V = 2.16 km / h = 2.16 * 1000/3600 m / s = 0.6 m / s; t = 0.5 min = 0.5 * 60 s = 30 s.
To determine the height of a house under construction, it is necessary to calculate the product of the speed of lifting the load and the time spent on this rise:
H = V * t = 0.6 * 30 = 18 m.
Answer: The height of the house under construction is 18 meters.
