Answer: This turn will make a change of 45 minutes.
Step-by-step explanation: Now, a full turn of the minute hand in a clock face is an hour or 60 minutes.
Now, if we only do a 3/4 of a turn, the number of minutes passed is equal to:
3/4*60min = 45min
So in a 3/4 turn of the minute hand, the "change" in the time will be one of 45 minutes.
