Anand starts from a point P towards point Q, where PQ = 50 km. After 1 hour, Ram starts from P and catches up with Anand after 2 more hours. After meeting they continue to travel towards Q. On reaching Q, Ram reverses his direction and meets Anand 6 hours after the first meeting. Find Anand's speed.	Choose the correct choice from the following.
A) (45/7) kmph B) (100/21) kmph C) (40/7) kmph D) (30/7) kmph E) (65/7) kmph
Let the first meeting point be at a distance of x km from P, the remaining distance until Q would be (50-x) km   Anand traveled this x kms in 3 hours, making his speed x/3 kmph   Ram traveled the same x kms in 2 hours, making his speed x/2 kmph   So, in 6 hours:   Anand will cover=6x/3=2x km   Ram will cover6 /3=

2x km   Ram will cover=6x/2=3x km   And between their first meeting point and second, they both together covered a distance of 2(90-x) km.   2x+3x6 /2=

3x km   And between their first meeting point and second, they both together covered a distance of 2(90-x) km.   2x+3x=2(50-x)   5x=100-2x   7x=100   x=100/7 km   Anand's speed=x/3=100/(3*7)=100/21 kmph   Ans:(100/21) kmph
