La fórmula para calcular la distancia de "d" en pies, necesaria para detener un auto sobre una superficie con nieve es d=1/6 x^2, donde x es la velocidad del auto en millas por hora, antes de que se apliquen los frenos. si la distancia necesaria para detener un auto fue de 150 pies, ¿cual era la velocidad del auto antes de que de aplicarán los frenos?

con planteamiento, porfavor.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
