Which equation describes average speed?

A-Average speed = Total distance x Total time

B-Average speed = Sum of instantaneous speeds

C-Average speed = Total distance ÷ Total time

D-Average speed = Total time ÷ Total distance



Answer :

The correct equation would be C

Answer:The correct answer is option (C).

Explanation:

Average speed is defined as total distance covered by the body divide by the time elapsed( passed).

[tex]\text{Average speed}=\frac{\text{Total distance}}{\text{Time Elapsed}}[/tex]

Suppose body has covered [tex]D_1[/tex] distance in [tex]T_1[/tex] first interval and after it covered [tex]D_2[/tex] distance in [tex]T_2[/tex]  in second interval. So, the Average speed will be ;

[tex]\text{Average speed}=\frac{D_1+D_2}{T_1+T_2}[/tex]

Hence ,the correct answer is option (C.).
