您如何计算以百分比表示的时间X比时间Y快多少时间? [英] How do you calculate how much faster time X is from time Y in terms of %?

问题描述

在我的办公室，我们对如何解释此问题存有争议.

We're having a bit of a dispute at my office as to how this question should be interpreted.

**时间1 = 0.6053秒 时间2 = 1.3477秒

**Time 1 = 0.6053 seconds Time 2 = 1.3477 seconds

时间1到时间2快百分之几?**

What percentage faster is time1 to time 2?**

我相信，如果您的时间为X秒. X/2(一半时间)快了100％.

I am of the believe that if you have a time of X seconds. X/2 (half as long) is 100% faster.

我对此问题的解决方案计算为

My solution to this problem is calculated as

(T2/T1)-1

1.3477/.6053-1 = 1.2265

1.3477/.6053 - 1 = 1.2265

其他人说，您应该将它们视为数字并像

Other people are saying that you should just look at these as numbers and calculate it like

1-(T1/T2)

1- .6053/1.3477 = .5508

1- .6053/1.3477 = .5508

(以上答案为四舍五入).

(the answers above are rounded).

推荐答案

使用整数更容易.

让我们说X = 100和Y = 50

Lets say X = 100 and Y = 50

您说的是时间1到时间2快百分之几?"这意味着，从时间2开始，时间1快了多少...再次，以时间2为参考点，时间1如何比较.

You're saying "What percentage faster is time 1 to time 2?" This means, with respect from time 2, how much faster is time 1... Again, using time 2 as the reference point, how does time 1 compare.

因此，您将使用:T1/T2 =(100/50)=两倍的速度= 200％

So for this, you would use: T1 / T2 = (100 / 50) = twice as fast = 200%

在上述情况下，X< Y，因此该百分比将小于100％.快了44.9％.

In your case above, X < Y so it would be a percentage less than 100%. Roughly 44.9% faster.
