Best ResponseYou've already chosen the best response.020/40 = 2/4 = 1/2 = 1 object every 2 minutes

Best ResponseYou've already chosen the best response.1okay so if Jack makes 2x objects in 40 minutes, how long will it take for him to make 1 object?

Best ResponseYou've already chosen the best response.1No. Suppose you make 1 object in 2 minutes. How long will you take to make 5 objects?

Best ResponseYou've already chosen the best response.1Yes! So if Jack makes x objects in 20 minutes How long will it take for him to make 5x objects?

Best ResponseYou've already chosen the best response.1Sorry, 6x objects I meant

Best ResponseYou've already chosen the best response.1If he makes x objects in 20 minutes Then how can he possibly make 6 times the number of objects that he took 20 minutes to make, in 4 minutes?

Best ResponseYou've already chosen the best response.1for 5x it is 100 for 6x it is 120

Best ResponseYou've already chosen the best response.1Okay treat the question like this: I make 1 object in 24 minutes On the other hand, you take 20 minutes to make the same object. Then tell me now, How long will I take to make 5 such objects? How long will you take to make 6 such objects?

Best ResponseYou've already chosen the best response.1In this case, it's like a variable, for example: Let's take x = 1 , and replace the x with 1 and read the question once again: Working at a constant rate, Bob can produce 1/3 widgets in 8 minutes. Working at a constant rate, Jack can produce 2 widgets in 40 minutes, where 1>0. Which of the following is greater: a. The number of minutes it will take Bob to produce 5 widgets. b. The number of minutes it will take Jack to produce 6 widgets.

Best ResponseYou've already chosen the best response.1Or if you want take x = 2 or x = 3 or 4 or so on, it's an alphabet which you can replace with positive numbers

Best ResponseYou've already chosen the best response.1PLEASE NOTE: Here x is not equal to 24 or 20 It means the time taken by Bob to make x objects is 24 minutes and the time taken by Jack to make x objects is 20 minutes
