Sorry Im really bad at maths, could you explain to me in detail how you would figure this out, Thanks.2 bulldozers can move an mount of soil in 9 hours. How long will it take 3 bulldozers
Math isn't always logical. It's 9/2, times 3. 4.5*3 = 13.5 Doesn't matter if it's logical. But...bulldozers knock things down...not move soil...
Okay, well, first, it's math, not maths. Maths isn't even a word. Divide nine by two. That's the rate at which one bulldozer works. Multiply by three. I think; I may have misread or misunderstood. It's one over here...
13.5 is wrong! THE ANSWER: 6 hours It takes 2 bulldozers 9hrs to find the amount for 3 bulldozers: divide 2 by 3 = 0.6667 then multiply by 9 = 6 And there you go :)
Using 2 bulldozers would cut the amount of time it takes 1 bulldozer to move the soil in half, so to find how long it would take 1 bulldozer to move the soil you have to take 9 plus 9 and get 18. Using three bulldozers would take 1/3 of the time it would 1 bulldozer to move the soil. If it takes 1 bulldozer 18 hours then you would divide that by 3 and get 6. So it would take 3 bulldozers 6 hours. Everyone else is wrong. Why would it take 3 bulldozers more time to move the soil than 2?
13.5 hours 9 divided by 2 =4.5 9+4.5=13.5
