Question

A circular field has a circunference of 360 km. Two cyclists Aayush and Anuj start together and
can cycle at speeds of 12 km/her and 15 km/hr, respectively, round the circular field. After how
many hours will they meet again at starting point?​

Answer 1

▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

$\huge\bold{\underline{\underline{{Answer:-}}}}$

Aayush is the faster cyclist. When Aayush crosses Anuj he would have travelled the entire circular field more than Anuj and will then be able to cross him and meet him again. 

Aayush completes one more round than Anuj and when they meet he is one more round ahead of him, which in turn means that he has travelled 360 kms more than Anuj when they meet.

$\huge{\boxed{\rm{\red{Example}}}}$

Let the time at which they meet be equal to 't'.

⇨15×t−12×t=360

⇨3×t=360

$\implies\boxed{\bf<strong>⇨</strong>Thus t=120 hours. }$
