Question

it takes 8 machines to do one job in 6 days. How many machines does it take to do the same job in 4 hours?

I got 288, I just need someone to check!!! :D

Answer 1

6 days = 36 times of 4 hours.

So if you would need 8 machines to be done in 6 days, then to be done 36 times faster you will need 36 times more cars.

Answer 2

so 288, right? That's kinda how I worked it out
8 machines take 144 hours to do 1 job. You want to do the job in 1/36th the time (4 hours) so you have to add 36 times as much machines

Answer 3

That's what I am thinking to, but I had a doubt, b/c the number is kind of wierd.

Answer 4

8 machines can do one job in 6 days
8 machines can thus do 1/6 th of a job in 1 day
8 machines can thus do 1/6 x 1/6 of a job or 1/36th of a job in 4 hours
But we need 36 times that.
So yeah...8 x 36 = your answer...

Answer 5

THANKS GUYS! :D
