In 1 h the minute hand on a clock moves through a complete circle, and the hour hand moves through 1 12 of a circle. Through how many radians do the minute hand and the hour hand move between 1:00 p.m. and 1:45 p.m. (on the same day)?

Answer:3/2π and π/480Step-by-step explanation:The question given says that the minute hand on a clock moves through  complete circle in 1 hour, that is 360° or 2π. It also says that the hour hand moves through 1/12 of a circle, that means 30° or π/6.To know how many radians do the minute hand and the hour hand move between 1:00 p.m. and 1:45 p.m, it's necessary to calculate how many radians move them per minute.Between 1:00 p.m. and 1:45 p.m 45 minutes have passed. With that information, the radians can be calculated using multiplication and division.Minute hand: To know how many radians move the minute hand per minute division wil be used. Movement in an hour/ minutes in an hour2π rad/60 min= π/30 rad-minThat means the minute hand move π/30 radians in a minute.Now, multiplication can be used to calculate how many radians move the minute hand in 1h.(π/30 rad-min)(45 minutes)= 3/2π radThe minute hand moves 3/2π radians between 1:00 p.m. and 1:45 p.m.Hour hand: To know how many radians move the hour hand per minute division wil be used. Movement in an hour/ minutes in an hour2π rad/(60 min x 12 hours)= π/360 rad-minThat means the minute hand move π/360 radians in a minute.Now, multiplication can be used to calculate how many radians move the hour hand in 1h.(π/360 rad-min)(45 minutes)= π/8 radThe minute hand moves π/8 radians between 1:00 p.m. and 1:45 p.m.
