Respuesta :

calculista

we know that

the average speed is equal to

[tex]average\ speed =\frac{distance}{time}[/tex]

in this problem we have

[tex]distance=1.50\ miles\\ time=143\ seconds[/tex]

substitute the values in the formula

[tex]average\ speed =\frac{1.5}{143}[/tex]

[tex]average\ speed =0.01\frac{miles}{seconds}[/tex]
