How to find the total amount of miles driven?

The total amount of miles driven is given by the addition of the number of miles driven on Friday, Saturday and Sunday.

The separate amounts are given as follows:

  • Friday: 138 miles.
  • Saturday: 225 miles.
  • Sunday: x miles.
  • Total: 482 miles.

Hence the equation that matches the given situation is:

138 + 225 + x = 482.

Solving the equation, we have that:

x = 482 - (138 + 225)

119.
