While Sonia takes a walk, Rahul rides his bicycle along with her in the same direction. As soon as they
pot out of the gate, Rahul rides towards the end of the road and rides back to Sonia. He repeats this
one more time (2 rounds in total), riding at a uniform speed. After the second time, both of them walk
last 45 meters together, the total distance between their house gate and the end of the road is 125
meters. Sonia walks at the rate of 4 m/sec What is the cycling, speed of Rahul?
O

16 km/hr
20 km/h

• Time for Sonia to cover 1 round (125 m) distance = 125/4 sec
  And
  In the same time Rahul covers 2 rounds; so Rahul speed will be = 2*125/(125/4) = 8m/s
