Question

A, B and C start cycling around a circular path in
the same direction at the same time. Circumference
of the path is 1980 m. If the speed of A is 3 m/minutes,
speed of B is 198 m/min and that Of C is 220 m/minutes and
they start from same point, then after what
time they will be togather at the starting point​

Answer 1

Step-by-step explanation:

speed = distance /time

time taken by A=660 min

time taken by B=10min

time taken byC=9 min

LCM of 660 ,10,and 9 is 1980

so after 1980 min they will be together at starting point
