Answer 1

Answer:

11%

Step-by-step explanation:

To find the percentage of this question, you simply take the previous speed and divide it by the current speed. Then, multiply it by 100 and then subtract it from 100. We subtract it by 100 because the number that we get is how fast the launcher is.

So basically:

so, 100 - (65.537 ÷ 73.372 * 100)

so, 100 - (0.89 * 100)

so, 100 - 89

therefore, 11%

Therefore, The previous rocket launcher was 11% slower than the Current (and Upgraded One).
