Question

a wheel makes 20 revolutions per min. how many revolutions does it make per second? type and integer or simplified fraction.

Answer 1

1200 revolutions per second

Explanation:

60 seconds per minute so multiply 60 x 20 to get 1,200

Answer 2

Answer:
1/3
Step by step:
Since the wheel is rotating at 20 revolutions per minute, to find the amount of rev’s per second would go as follows:

20/min = ?/second

convert each denominator to numerical form referring to seconds

20/60 = ?/1

Simplify

1/3 = ?/1

Find value of ?

1/3 = (1/3)/1

Simplify both sides completely

1/3 = 1/3

1/3
