Q1. A particular guitar string is supposed to vibrate at 214 Hz, but it is measured to actually vibrate at 272 Hz. By what percentage must the tension in string be changed to get the frequency to the accurate value?

Q2. Larry leaves home at 12:04 and runs at the constant speed to the lamppost. He reaches the lamppost at 12:11, immediately turns, and runs to the tree. Larry arrives at the tree at 12:24. What is Larry's average velocity during his trip from home to lamppost, if the lamppost is 389.0 m west of home, and the tree is 670.0 m east of home?

What is an average velocity for Larry's entire run?
