Question

An object travels 16 m in 4 sec and then another 16 min in 2 sec. Ehat is the average speed of the object

Answer 1

Correct Question:-

An object travels 16 m in 4 sec and then another 16 m in 2 sec. What is the average speed of the object

Distance in case 1 = D₁ = 16 m

Distance in case 2 = D₂ = 16 m

Time in case 1 = T₁ = 4 s

Time in case 2 = T₂ = 2 s

${\boxed{\sf Average\; speed = \dfrac{Total \;distance}{Total\; time}}}$

$\sf\longmapsto Avg. \;Speed=\dfrac{(16+16)}{(4+2)}$

$\sf\longmapsto Avg. \;Speed= \dfrac{32}{6}$

$\sf\longmapsto Avg. \;Speed= 5.33\; m/s$

Avergae speed is 5.33 m/s
