hello iamgodofdeath131

to answer such questions u have to find the relative speeds;

Angle made by the hours hand in 1 hour=360(degrees)/12(hrs)=30(degrees)

lly the angle made by the hours hand in 1 min = 1/2 degrees

the angle made by the minutes hand in 1 min = 360/60=6 degrees

hence the relative speed= 5 1/2 degrees per minute.

U make use of the formula TIME TAKEN BY THE TWO HANDS TO COVER x degrees = ANGLE COVERED/RELATIVE SPEED
