Consider the following predicates: speed(ford,100) speed(chevy 105). speed(dodge,95). speed(volvo,80). time(ford,20). time(chevy,21). time(dodge 24). time(volvo 24). distance(XY) speed(X,Speed). time(X,Time), Y is Speed Time. State whether the query is true or list all of the substitution(s) that make the query true: ?- speed(volvo.X)
