Si un auto avanza a 42 mph, ¿cuánto tiempo tarda en avanzar 105 millas?

¡Hola!

Tenemos los siguientes datos :

V (velocidad media) = 42 mph (millas / hora)

ΔS (distancia) = 105 millas

ΔT (tiempo) = ?

(en horas)

Aplicamos los datos a la fórmula de la velocidad media escalar, veamos : <img src="https://tex.z-dn.net/?f=%20Vm%20%3D%20%5Cdfrac%7B%5CDelta%7BS%7D%7D%7B%5CDelta%7BT%7D%7D%20%20" /><img src="https://tex.z-dn.net/?f=%2042%5C%3Amilhas%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5Cdfrac%7B%5Chspace%7B1.1cm%7D%7D%7B~%7D%2Fhoras%20%3D%20%5Cdfrac%7B105%5C%3Amilhas%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5Cdfrac%7B%5Chspace%7B1.1cm%7D%7D%7B~%7D%7D%7B%5CDelta%7BT%7D%7D%20%20" /><img src="https://tex.z-dn.net/?f=%2042%2A%5CDelta%7BT%7D%20%3D%20105%20" /><img src="https://tex.z-dn.net/?f=%20%5CDelta%7BT%7D%20%3D%20%5Cdfrac%7B105%7D%7B42%7D%20%20" /><img src="https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Cboxed%7B%5CDelta%7BT%7D%20%3D%202.5%5C%3Ahoras%7D%7D%5Clongleftarrow%28tiempo%29%5Cend%7Barray%7D%7D%5Cqquad%5Ccheckmark%20" />¡Espero haberte ayudado, saludos.
