P.3.A hyperbola cuts the base line 60 Km from the Master end and 150 Km from the Slave end. When on the same hyperbola at a range of 90 Km from the Master, the range from the Slave will be:
A)300 km B)150 km C)240 km D)180 km
Soln:
Let one arm of hyperbola be Master(M) and other arm as Slave(S).
Center(O)
Given: MO=60 and SO= 150.
Hence the distance between the two arms of hyperbola i.e. MS=150-60=90 (which is a constant)
Same parabola, new location Mi and Si. Although with same center and MS=90
MiO= 90
Thus, MiO + 90 = SiO = Range of Slave = 180
