The rays om , on , and op in the figure, coincide at time t=0. at the same instant of time om and op rotate in the plane about point o in opposite directions while on remains fixed. with respect to on , segment om rotates at constant rate of 3° per second and op , at 6° per second. what is the smallest positive value of t, in seconds, for which segments om and op will coincide? when t=30 min, how many more revolutions does segment op complete than segment om ?
