Problema Solution
A family drove 1000 miles in 2 days of their vacation. if the distance driven on the second days was two-thirds the distance driven on the first, how far did they driven on each of the days?
Answer provided by our tutors
let
x = the distance driven of the first day in miles
y = the distance driven of the second day in miles
the family drove 1000 miles in 2 days
x + y = 1000
the distance driven on the second days was two-thirds the distance driven on the first
y = (2/3)*x
by solving the system of equations
y = (2/3)*x
x + y = 1000
we find
x = 600 miles
y = 400 miles.
on the first day they drove 600 miles.
on the second day they drove 400 miles.
