Answer:
Step-by-step explanation:
Distance = 5 km
Speed of A = 212 km/hr Time taken by A = 5/5×2=5hours
Speed of B = 3 km/hr Time taken by B = 5/3hours
Speed of C = 2 km/hr Time taken by C = 5/2hours
LCM of numerator ÷ HCF of denominator
=2, 5/3, 5/2
LCM = 10/1
=10
They will meet again after 10 hours
