Question

A clock's minute hand moves 60 grade in 10 minutes and 180 grade in 30 minutes low far does it move from 11:00 to 11:40? What do you need to know to solve the problem? What is the measure of the angle from 11:00 to 11:30?- What is the measure of the angle from 11:30 to 11:40

Answer 1

11 to 11.40 is 40 minutes.  So if the minute hand moves 60 in 10 minutes, it would move 240 in 40 minutes.
The angle between 11 and 11.30 is 180 degrees.
The angle between 11.30 and 11.40 is 10 minutes, so the angel is 60 degrees, the same as the first bit of information in the quesiton.
