2. Vol. of Tank =Vol of water from pipe. Apply formula to get length of pipe. It should be 100m. Then use this value as distance in formula Speed =Distance/Time. Use conversions to change km/hr to m/s. The answer should be 0.77 seconds
Thanks anjalismenon

3. speed of boat =18km/hr. speed of stream =x. Time taken to go upstream=24/18-x. Time taken to go downstream=24/18+x. Therefore, required eq.>> 24/18-x - 24/18+x = 1. >> x^2+48x-324=0. factorising, (x-6)(x+54)=0. >> x=6km/hr or x=-54km/hr(which is not possible. Therefore speed of stream =6km/hr
