Answer:

the shortest distance between P and Q is 12 km

Step-by-step explanation:

Answer 2

Answer:

13 km

Step-by-step explanation:

Let the distance covered by Sudha from point  P to point Q = 12km

From Q she travelled  5 km towards south and reach the point R. Join PR

The shortest distance between the points P and  Q is given by PR

Now we get a right triangle. PR =( PQ^2+QR^2)^1.2

PR = (144 + 25)^1/2

PR =13 km
