Question

Question 7: 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?​

Answer 1

Answer:

Given:

Speed of Guru = 4km

Speed of Chela = 5km

Circumference of circular path = 115km

To Find:

When will both of them meet ?

Solution

Relative speed of Guru and Chela = 5 - 4 = 1

Time = Distance/ Speed

Thus,

They will meet after = 115/1

= 115

Also, Chela is the faster person. He gains 1 km in 1 hour.

Thus, Chela will gain one complete round over guru in 115 hours, which means they will meet after 115 hours.

Answer: They both will meet after 115 hours from the starting point
