Let the distance between Delhi and Noida is X km and Krishna's speed is d km/hr.
When they met for the first time, Distance covered by Krishna = d km
Distance covered by Shruti = 2X-d km
So the ratio of speeds of Shruti and Krishna is 2X - d : d ...(1)
Between 1st and 2nd meeting, Distance covered by Krishna = d/2 km
So distance covered by Shruti will be = (X-d)+(X-3d/2)= 2X-5d/2
So the ratio of speeds of Shruti and Krishna in this case will be 2X-5d/2 : d/2 ...(2)
By equating (1) and (2)
Therefore the distance between Delhi and Noida is 2d and Krishna will take 2 hours to cover that distance with speed of d km/hr.
