A particle travelled first 10 m with 2 m/s, next 10 m with 3 m/s and last 10 m with 6m/s then its average speed is??

Answers (1)

Average speed =\frac{\text { total distance travelled }}{\text { total time taken }}=\frac{(10+10+10) \mathrm{m}}{(\frac{10}{2}+\frac{10}{3}+\frac{10}{6}) \mathrm{s}}=\frac{30}{10}= 3 \mathrm{m} / \mathrm{s}$
