Question

If a globe rotates through 150 degrees in 5 seconds, how many rotations does it make in 30 seconds

Answer 1

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.

Answer 2

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.
