Answer 1

Answer:

The speed is 19 m/min and velocity is 7 m/min.

Explanation:

The speed is given as,

$\text{speed}=\frac{\text{total distance travelled}}{\text{total time taken}}$

Substituting all known values,

$\text{speed}=\frac{\text{KL+LM+MN}}{10\text{ min}}\\=\frac{\text{(20 m+50 m+10 m)+(10 m+50 m)+50 m}}{10\text{ min}}\\=\frac{190\text{ m}}{10\texr{ min}}\\=19\text{ m/min}$

The velocity is given as.

$\text{velocity}=\frac{\text{net displacement}}{\text{total time}}\\=\frac{\text{KN}}{\text{10 min}}\\=\frac{70\text{ m}}{10\text{ min}}\\=7\text{ m/min}$
