7 X 20 = 140 amp hours

140 amp hours / 45 amps = 3.11 hours

Maybe 0. depends on the source, any fuses or breakers in the line, and wiring. If that is all good the answer is a simple (7/45)x20.
There is no standard and it depends on how hard you are running it. Check the manual and it will tell you current consumption.
