Question

Math Analysis:
A fan spins 100 times in 1 minute. Through how many degrees does a point on the tip of the wheel move in 15 seconds?

Answer 1

15 seconds is 1/4 of a minute.
Then it'd spin 25 times because 25 is 1/4 of 100.
One turn is 360 degrees so:
\( \color{Black}{\Rightarrow 25 \times 360 }\)

Answer 2

1minute =60seconds
60=15*4
so In 15seconds it turn for 100/4=25
Angle turned= 25*360

Answer 3

isn't there a formula for this :P
