problem

Two bicycle racers cross the starting line on a circular track at 12:15 PM. One cyclist takes 1212 minutes per lap, while the other completes a lap every 1616 minutes. Assuming their speeds remain constant, what is the next time they cross the starting line together? Your answer should be in the form h:m1m2,h:m_1m_2, like 3:45.
Plain-text mathematical notation (without MathML)
Two bicycle racers cross the starting line on a circular track at 12:15 PM. One cyclist takes 12 minutes per lap, while the other completes a lap every 16 minutes. Assuming their speeds remain constant, what is the next time they cross the starting line together?  Your answer should be in the form h:m₁m₂, like 3:45.
Original LaTeX notation
Two bicycle racers cross the starting line on a circular track at 12:15 PM. One cyclist takes $12$ minutes per lap, while the other completes a lap every $16$ minutes. Assuming their speeds remain constant, what is the next time they cross the starting line together?  Your answer should be in the form $h:m_1m_2,$ like 3:45.
