Three identical pumps fill 50,400 liters of diesel into the tank in 7 hours. How much more (less) diesel
will they pump if we add two more pumps, and they will all work for 4 hours?

Correct answer:

Δ =  -2400 l

Step-by-step explanation:

V1=50400 l t1=7 h Q=3 t1V1=3 750400=2400 l/h  t2=4 h V2=Q (2+3) t2=2400 (2+3) 4=48000 l  Δ=V2V1=4800050400=2400 l
