Question

If a bottle rotates through 270 degrees in 3 seconds how many degrees does it rotate in 2 seconds

Answer 1

The bottle rotates 180 degrees in 2 seconds.

I divided 270 by 3, which was 90. Then, I multiplied 90 by 2. Which was 180.

Answer 2

270 / 3 = 90
90 sec per spin
then you multply by two for two spins

90x2=180

Answer is 180 per sec
