Question

If a blade af a fan turns 12 times every 4 second , how many times would it turn in a minute?​

Answer 1

Answer:

180 times.

Step-by-step explanation:

First we divide to find out how many times it rotates in a second, so we divide 4 with 12, which is 3, then as we know that there are 60 seconds in a minute, that's why we then multiply that 3 with 60 to find out how many times it rotates in a minute, yep! it's 180 times that's the answer,and that was a unitary method question.
