First find for 1 second = 150/50 = 30 so, in 1 second it rotates 30 degrees Now, multiply 30 degrees with 30 seconds 30 x 30 = 900 So, in 30 seconds it rotates 900 degrees. Hope it was Helpful !!!!!!!
We know that the globe makes a 150 degrees rotation in 5 seconds. To find how many rotations he does we do: 30/5=6 Then we do 6×150=900. Then we divide 900 by 360=2.5 So the globe does a 2.5 rotations.
