Three friends drove southeast to New Mexico.
Kyle drove half as far as Jamaal.
Assume Kyle drove x miles
Jamaal drove 2x miles
Conner drove 4 times as far as Kyle.
Kyle drove 4x miles
x+2x+4x = 476
7x =476
x= 476/7=68
Kyle 68 miles
Jamaal drove 2x = 2*68= 136 miles
Conner drove 4x miles = 4*68 = 272 miles
68+136+272 =476

Most convenient is give Kyle's distance a variable.
Kyle              k
Jamaal           2k
Conner           4k
TOTAL            476

k%2B2k%2B4k=476----------solve....
