An airplane is in steady level flight with a true air speed of $50 \mathrm{~m} / \mathrm{s}$. The ambient air density and ambient pressure at the flight altitude are $0.91 \mathrm{~kg} / \mathrm{m}^{3}$ and $7 \times 10^{4} \mathrm{~N} / \mathrm{m}^{2},$ respectively. At sea level, air density is $1.225 \mathrm{~kg} / \mathrm{m}^{3}$ and ambient pressure is $1.01 \times 10^{5} \mathrm{~N} / \mathrm{m}^{2}$. The equivalent or indicated air speed of the airplane is____________$\quad \mathrm{m} / \mathrm{s}$ (round off to 2 decimal places).
