the racing magic takes 60 seconds to circle the racing track once . the charging bull makes 40 rounds of the track in an hour . if they left the starting point together , how many minutes will it take for them to meet at the starting point for the second time ?
time taken by racing magic to make one circle = 60 seconds time taken bycharging bullto make one circle = 60 mins / 40 = 1.5 mins = 90 seconds lcm of 90 and 60 seconds = 180 seconds time taken for them to meet at the starting point for the second time = 180 * 2 = 360 seconds = 6 mins answer b
multiply(divide(multiply(multiply(const_60, divide(60, 40)), const_2), const_60), const_2)
