Solution



Given:
    • A wheel makes 6000 revolutions in every minute

To find:
    • Number of revolutions the wheel make in x seconds

Approach and Working:
    • As the wheel makes 6000 revolutions in a minute or 60 seconds time, in 1 second it will make \(\frac{6000}{60}\) = 100 revolutions
    • Therefore, in x seconds, the wheel will make 100 * x = 100x revolutions

Hence, the correct answer is option B.

At the rate of 6,000 revolutions per minute, how many revolutions will a wheel make in x seconds?

A. \(6,000x\)

B. \(100x\)

C. \(\frac{100}{x}\)

D. \(\frac{6,000}{x}\)

E. \(\frac{360,000}{x}\)

Since x seconds = x/60 minutes, the number of revolutions made is 6000 * x/60 = 100x revolutions.

Answer: B
