Rohit and Riya started walking toward each others from X and Y at the speed of 14 km/hr and 10 km/hr respectively. Rohit had walked 625 m more than Riya. Find the distance between A and B.
Answer & explanation
Correct answer: option 3
x ⇐ ⇒ y
Rohit → 14 km/h Riya → 10 km/h
⇒ ⇐
Let both travelled for x hours
Distance covered by Rohit = 14 x
Distance covered by Riya = 10 x
14 x - 10 x = .625
4 x = .625
x = .15625 h
Distance covered by Rohit = 14 x = 14 × .15625
= 2.1875
Distance covered by Riya = 10x = 10 × .15625
= 1.5625
Total distance between A & B = 2.1875 + 1.5625
= 3.75 km
