A, B and C start walking together from one place to walk around a circular island with a circumference of 30 km. A and B move in the same direction and C moves in the opposite direction. If A runs 5 km/h, B runs 7 km/h and C runs 8 km/h, then after how long will they meet together?
Answer & explanation
Correct answer: option 2
\(\frac{30}{5}\), \(\frac{30}{7}\), \(\frac{30}{8}\)
LCM = \(\frac{LCM}{HCF}\) = \(\frac{30}{1}\) = 30 Hours
They will meet after = 30 Hours
