Vince begin practicing up on a piano at 5:15 p. m. he stopped playing at 5:35 p. m. how many degrees did the minute hand turn during vince's

practice time explain how you found your answer.

Since you must turn 360 degrees to get around a full hour (60 minutes) we know that 10 minutes = 60 degrees of change because 360 / 6 = 60. Vince played piano for 20 minutes (5:15 - 5:35), and 2 x 10 = 20, so to ensure the equation 10 (minutes) = 60 (degrees) stays equivalent, we'll multiply 60 by 2 too. 60 x 2 = 120, so the minute hand turned 120 degrees during Vince's practice time.

The minute hand turned 120 defrees.

For every 5 minutes, minute hand will turn 30 degrees as it takes 12 times 5 minutes to complete one round (one hr), which is 360 degrees. For Every 15 minutes, it turns 90 defrees.

So from 5.15 to 5.35pm, the minute had turned 20 minutes, that is 4 times of 5 minutes.

4 times of 5 minutes is equal to 4 times of 30 degrees, since it turns 30 degress for every 5 minutes.

So it has turned 120 degrees to move from 5.15 pm to 5.35 pm
