I read an article recently online that is about the effect of coronavirus pandemic. One of men said in an interview that "As restaurants come back online, we're anxious to see what that ramp is," "You know, we don't know if that ramp is going to be back to 100 percent in one month, or is it six months?"
I looked up in the dictionary for the word "ramp", and all the meanings seem not applicable in the sentence above. Does ramp have an another meaning except sloping surface or slip road?
