Question 409062
driving at an average speed of {{{v=50 (miles/ hour)}}} the trip will take {{{t=22 hours}}}

{{{s=vt}}}

{{{s=50(miles/hour)22hour}}}


{{{s=50(miles/cross(hour))22cross(hour)}}}

{{{s=50*22miles}}}

{{{s=1100miles}}}............the number of miles one way


{{{1100miles=1770.2784000000001km}}}.......the total distance from miles to kilometers



if the family car uses {{{6.3 L}}} of gas per {{{100km}}}, for distance {{{1770.2784000000001km}}} they will need  

{{{((6.3L/cross(km))(1770.2784000000001cross(km))/100))}}}


={{{(6.3L)17.702784000000001=111.53L}}}..of gas are needed
