Question

A scientist found that x grams of Metal A is completely oxidized in 2x13 seconds and x grams of Metal B is completely oxidized in 6x13 seconds. How much faster is Metal A oxidized than Metal B?

Answer 1

Answer: Metal A is 3 times faster than Metal B.

Explanation:

Since we have given that

Time taken to oxidised metal A =
`2x√(3)\ seconds`

Time taken to oxidised metal B =
`6x√(3)` seconds

So, ratio of metal A to metal B would be

`(Metal\ A)/(Metal\ B)=(2x√(3))/(6x√(3))=(1)/(3)`

So, Ratio of Metal A to Metal B is 1 : 3.

Hence, Metal A is 3 times faster than Metal B.
