How many revolutions does a merry go round make during 6,5 min if its average rotation speed is 2,4 r.p.m?
rev = (6.5 min)(2.4 rpm) = 15.6 rev
To find the number of revolutions a merry-go-round makes during a specific time, you need to multiply its rotation speed by the duration of time.
Given:
Rotation speed = 2.4 revolutions per minute
Time = 6.5 minutes
To find the number of revolutions, multiply the rotation speed by the time:
Number of revolutions = Rotation speed × Time
Substituting the values given:
Number of revolutions = 2.4 r.p.m × 6.5 min
Now, perform the multiplication:
Number of revolutions = 15.6 revolutions
Therefore, a merry-go-round makes approximately 15.6 revolutions during 6.5 minutes.
