Respuesta :

calculista

we know that

the speed's formula is equal to

[tex]speed=distance/time[/tex]

in this problem we have

[tex]distance=84\ miles\\time=2\ hours[/tex]

Substitute the values in the formula

[tex]speed=84/2[/tex]

[tex]speed=42\frac{miles}{hour}[/tex]

therefore

the answer is

[tex]42\frac{miles}{hour}[/tex]
