India's Mangalyan was sent to the Mars by launching it into a transfer orbit EOM around the sun. It leaves the earth at $E$ and meets Mars at $M$ . If the semi-major axis of Earth's orbit is $a_{e} = 1.5 \times 1 0^{11} m$ , that of Mar's orbit $a_{m} = 2.28 \times 1 0^{11} m$ , taking Kepler's laws, give the estimate of time for Mangalyan to reach Mars from Earth.
