Guru and Chela walk around a circular path of 115 km in circumference, they start together from the same point. If they walk at speed of 4 and 5 kmph respectively, also they walk in the same direction, when will they meet?

After 115 hours

After 125 hours

After 120 hours

After 210 hours

Correct Option: 1

Since they're walking in the same direction:

\newline

- Relative speed =

5 - 4 = 1

kmph (Chela will catch up to Guru)

\newline

- Distance to catch up = Full circumference = 115 km

Using the formula: Time = Distance/Speed

Time = \frac{115}{1} = 115

hours

Therefore, they will meet after 115 hours.
