A body of mass 4 kg is placed on a plane at a point P having coordinate (3, 4) m. Under the action of force \(\overrightarrow{\mathrm{F}}=(2 \hat{\mathrm{i}}+3 \hat{\mathrm{j}}) \mathrm{N}\), it moves to a new point Q having coordinates (7, 10)m in 4 sec. The average power and instantaneous power at the end of 4 sec are in the ratio of :
