The degrees the hour hand must travel before she can go home is 270 degrees
How many degrees must the hour hand travel before she can go home?
From the question, we have the following parameters that can be used in our computation:
The watch
Where, we have
Angle between the current time and 4 : 15 = 30 * 9
Evaluate the product
Angle between the current time and 4 : 15 = 270
Hence, the degrees is 270 degrees
