1. Two towns are at a distance of 240km from each other. A motorist takes 8 hrs to cover the distance if he travels at a speed of Vo km/h from town A to an intermediate town C, and then continues on his way with an acceleration of x km/hr^2. He needs the same time to cover the whole distance if he travels from A to C at Vo km/h and from C to B at V1 km/h or from A to C at V1 km/h and from C to B at Vo km/h. Find Vo if the acceleration x i double Vo in magnitude and Vo not equal to V1

Guyz I might sound lame but can u share the method u wud use to find number of 5 digit multiples of 11 . A : 8181
My method is bit tedious n long
10000 (smallest 5 digit number) divide by 11 remainder 1 thr add 10 to get first 5 digit multiple of 11 ie 10010 and similarly find biggest 5 digit multiple of 11 ie 99990 and apply AP method to Find.
Or Can we divide no. of 5 digit numbers 90000 by 11 = 8181 (Does this always work )
