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.

Step-by-step explanation:

Since we have given that

Time taken to oxidised metal A  = $2x\sqrt{3}\ seconds$

Time taken to oxidised metal B = $6x\sqrt{3}$ seconds

So, ratio of metal A to metal B would be

$\dfrac{Metal\ A}{Metal\ B}=\dfrac{2x\sqrt{3}}{6x\sqrt{3}}=\dfrac{1}{3}$

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

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