Write $8.5×{10}^{3}$ in standard notation.

Hillary Hamilton

Distance travelled in west direction $\left({D}_{1}\right)=speed×time=5×10=50m$
Distance travelled in south direction $\left({D}_{2}\right)=speed×time=5×5=25m$
Displacement of the car $\left(s\right)=\sqrt{{50}^{2}+{25}^{2}}=55.9m$
Average velocity $\left(V\right)=\frac{\text{Total Displacement}}{\text{Total Time}}=3.73m/sec$
