Verified answer

Answer

total distance = 8

total time =26

avg speed = 8/26

avg velocity= 0/26

Solution :-

[tex]{\longmapsto}[/tex] Given to us that ,

• An object travels 8m (From A to C) [16sec]
• Come backs to A [10sec]

[tex]{\longmapsto}[/tex]We have to find ,

• The average speed

First finding the average speed ,

Formula =

[tex]{\sf{{ :\longmapsto{ \dfrac{total \: distance}{total \: time}}} }}[/tex]

Remember that , the distance must be in km and hr and m and sec the units should not be mixed

Total distance = 8 + 8 m = 16 m

Total Time = 16 + 10 = 26 sec

Putting the values,

[tex]{\sf{{ :\longmapsto{ \dfrac{16}{26}}} }} \\ \\ {\sf{{ :\longmapsto{ \dfrac{{\cancel{16}}}{{\cancel{26}}}}} }} \\ \\ {\sf{{ :\longmapsto{ \dfrac{8}{13}}} }}[/tex]

Therefore average speed ÷ 8/13 m/sec
