To find the rate in rotations per second, we need to divide the total number of rotations (770) by the total time in seconds.
The total time in seconds is 2 minutes, which is equal to 2 * 60 = 120 seconds.
So, the rate of rotation per second is 770 / 120 = <<770/120=6.4167>>6.4167 rotations per second.
A helicopter blade rotates 770 times in 2 minutes find the rate in rotation per second?

Sure! Imagine you have a helicopter blade. This blade rotates, or spins around, 770 times in 2 minutes. We want to find out how many times it rotates in just 1 second.
To solve this, we need to divide the total number of rotations (770) by the total time in seconds (which is 2 minutes, or 120 seconds). So, we take 770 and divide it by 120.
When we do the calculation, we find that the helicopter blade rotates about 6.4167 times in just 1 second. So, we can say that the rate, or speed, of the helicopter blade's rotation is 6.4167 rotations per second.
