Question

Ava started reading at 3:30 pm. she stopped for a snack at 4:15 pm . which fraction of a circle did the minute hand turn?

Answer 1

 I think the answer would be 3/4 because in 30 minutes it would turn halfway and in 15 it would be half a half and  half a half  is 3/4

Answer 2

3/4 because every 15 minutes is 1/4 and it went 45 minutes.
