Q2: A raft foundation of 20x60 m and depth of 1.2 m needs to be casted by concrete between 4 am and 10 am. The available equipment are as follows: pumps with a production rate of 90 m3/hr, concrete trucks with a capacity of 10 m3, and ready-mix concrete plants (factory) with a production rate of 120 m3/hr. Considering that the concrete trucks needs 30 minutes to complete one cycle (loading hauling, discharging and return), calculate the minimum numbers of pumps, concrete trucks and concrete plants required to complete the concrete casting within the specific time.
