Celia is staring at the clock waiting for school to end so that she can go to track practice. She notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.

Part 1: How many radians does the minute hand move from 1:25 to 1:50? (Hint: Find the number of degrees per minute first.)

How many radians does the minute hand move from 1:25 to 1:50?

Calculations are done as follows:

360 ° / 60 minutes = 6 ° per minute

1:25 to 1:50 = 25 minutes

25 minutes x 6 ° per minute = 150 °

150 ° (π / 180) = 5 π / 6
