3. (a) Two divers start at the surface and establish the following coordinate system: x is to the west,y is to the north, and z is down. Diver 1 swims 60 ft east, then 25 ft south, and then dives 30 ft. At the same time diver 2 dives 20 ft, swims east 30 ft and south 55 ft. Using MATLAB write a script file for following scenarios: (15) (i) Compute the distance bet diver 1 and starting point. (ii) How far in each direction must diver1 swim to reach diver 2?, (i) How far in a straight line must diver1 swim to reach diver2
