Question

116.A car moving on a straight road AD, it have to reach at a point B in the field at a perpendicular distance 'l' from point D. Velocity on road is 'V' and velocity on field is 'n'times slower than the velocity on road. Find the distance from point D where car turns it so that it reach point B in minimum time
