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 $\displaystyle \mathrm{a}_{\mathrm{e}}=1.5 \times 10^{11} \mathrm{~m}$, that of Mar's orbit $\displaystyle \mathrm{a}_{\mathrm{m}}=2.28 \times 10^{11} \mathrm{~m}$, taken Kepler's laws give the estimate of time for Mangalyan to reach Mars from Earth to be close to :
