From point A located on a highway (figure) one has to get by car as soon as possible to point B located in the field at a distance `l` from the highway. It is known that the car moves in the field `eta` times slower than on the highway. At what distance from point D one must turn off the highway?

From point A located on a highway, one has to get by a car as soon as possible to point B located in the field at a distance l from point D. If the car moves n times slower in the field, at what distance x from D one must turn off the highway.

A man in a car at location Q on a straight highway is moving with speed v. He decides to reach a point P in a field at a distance d from the highway (point M) as shown in the figure. Speed of the car in the field is half to that on the highway. What should be the distance RM, so that the time taken to reach P is minimum ?

A man in a car at location Q on a straight highway is moving with speed v He decides to reach a point P in a field at a distance d from the highway (point M) as shown in th e figure .
