Answer :
Rachel drove 503 miles on Saturday and 438 miles on Sunday
Solution:
Rachel drove 65 miles less on sunday than she did on saturday
Let x be the number of miles Rachel drove on Saturday
Let, x - 65 be the number of miles she drove on Sunday
Twice the miles driven on sunday is 373 more than the number of miles driven on saturday
Twice the miles driven on sunday = 373 + number of miles driven on saturday
2(x - 65) = 373 + x
Solve the above expression for "x"
2x - 130 = 373 + x
2x - x = 373 + 130
x = 503
Thus, x - 65 = 503 - 65 = 438
Thus, Rachel drove 503 miles on Saturday and 438 miles on Sunday
