An electric motor pumps water into a pool at a rate of 500 liters per hour. After a tune up, it's rate increases by x liters per hour. If the motor now takes 3 hours to pump 1800 liters, in which equation does x represent the increase in speed after the tune up?

Answer:

(500+x)*3=1800

Step-by-step explanation:

x will increase the rate so that the motor will pump 1800 liters in 3 hours, which makes x=100, and (500+100)*3=1800
